Love this? Pin it for later!
Bright, zesty, and bursting with Tex-Mex flair, this make-ahead chicken fajita salad has become my Monday-morning lifesaver more times than I can count. I first threw it together on a frantic Sunday when the week ahead loomed like a tidal wave of meetings, soccer practices, and late-night deadlines. One sheet pan, 25 minutes of roasting, and a quick whisk of lime dressing later, I had five colorful jars lined up on the counter—each one a promise that lunch was handled no matter how chaotic the day became. The smell of smoky paprika and sizzling peppers drifting through the kitchen felt like a tiny fiesta, and the first bite the next afternoon? Pure sunshine. Crisp romaine, caramelized peppers and onions, juicy cumin-kissed chicken, and that tangy lime dressing that somehow makes everything taste fresher. If you’re the kind of person who swears they “don’t do meal prep,” this recipe will convert you. It’s fast, flexible, and—best of all—no sad desk lunches. Whether you’re heading back to the office, packing poolside snacks, or just want dinner ready when you walk in the door, these jars (or bowls!) have your back.
Why This Recipe Works
- One-sheet-pan magic: chicken, peppers, and onions roast together while you shake the dressing—minimal dishes, maximum flavor.
- Layered jar method: keeps greens crisp for five full days; no more soggy salads by Wednesday.

- Freezer-friendly chicken: cook a double batch, freeze half, and future-you sends thanks.
Ingredients You'll Need
Great meal prep starts at the grocery store. Below are the stars of the show, plus my go-to swaps so you can shop your pantry first.
Chicken – I use boneless, skinless chicken breasts because they roast quickly and slice neatly. Thighs work if you prefer dark meat; just add 3–4 extra minutes in the oven. Look for plump, rosy pieces with no off smell. If your market sells the thin-cutlets, grab them—zero trimming required.
Bell Peppers – A mix of red and orange gives the sweetest, juaviest crunch. Green peppers are perfectly fine (and budget-friendly), but they lean more bitter. Choose specimens with taut, glossy skin; wrinkles mean they’re past prime and will steam instead of char.
Red Onion – It turns jammy and sweet in the oven, plus the purple hue looks gorgeous against the greens. Yellow onion subs in a pinch, but avoid white—they stay sharper.
Romaine Hearts – Crisp, hydrating, and sturdy enough to hold up for days. Skip pre-chopped bags that brown quickly. Wash, spin, and chop yourself for maximum freshness. Butter lettuce or kale are solid stand-ins; just massage kale with ½ tsp oil to soften.
Avocado Oil – High smoke point equals beautifully blistered veggies without the acrid taste of olive oil at 425 °F. Neutral flavor lets the spices sing. Sunflower or grapeseed oil are fine understudies.
Spice Rack MVPs – Chili powder, smoked paprika, ground cumin, oregano, garlic powder, and a whisper of cinnamon create that Tex-Mex soul. Check expiration dates; faded spices taste like dusty pantry air.
Lime – Bright acid wakes up every other flavor. Fresh-squeezed is non-negotiable; bottled carries a bitter aftertaste. Zest one lime into the dressing for extra punch.
Honey – Just enough to round the edges of the lime. Maple syrup or agave work for vegan tables.
Cilantro – Love-it-or-hate-it herb. If you’re in the soap-gene camp, swap flat-leaf parsley or thin-sliced green onions.
How to Make Meal Prep Chicken Fajita Salad With Lime Dressing
Make the fajita seasoning
In a small jar, combine 1 Tbsp chili powder, 2 tsp smoked paprika, 1½ tsp ground cumin, 1 tsp each kosher salt, garlic powder, and dried oregano, plus ¼ tsp freshly ground black pepper and a pinch of cinnamon. Shake until uniform. You’ll use 2 tsp per pound of chicken; the rest goes into the dressing and future taco nights.
Marinate the chicken
Pat 1½ lb chicken dry, place in a bowl, and drizzle with 1 Tbsp avocado oil and 2 tsp of the seasoning. Massage to coat every nook. Let rest 15 minutes while the oven preheats, or cover and refrigerate up to 24 hours for deeper flavor.
Prep the vegetables
Core and slice 2 bell peppers into ½-inch strips. Halve and peel 1 medium red onion, then cut into half-moons. Toss both on a rimmed sheet pan with 1 Tbsp avocado oil and 1 tsp of the fajita seasoning. Spread in a single layer so they roast, not steam.
Roast everything together
Slide the veggies onto the top rack and the chicken onto the middle rack of a 425 °F oven. Roast 18–22 minutes, flipping peppers once, until chicken hits 160 °F and peppers show charred edges. Remove, tent chicken with foil, rest 5 minutes, then slice across the grain into strips.
Blend the lime dressing
In a wide-mouth mason jar, combine 3 Tbsp fresh lime juice, 2 Tbsp honey, 1 tsp dijon, 1 tsp remaining fajita seasoning, and a pinch of salt. Let sit 2 minutes so honey dissolves, then add ¼ cup avocado oil. Screw on lid and shake vigorously until creamy and emulsified. Taste; add more lime or honey to balance.
Assemble the jars (meal-prep method)
Grab five 24-oz glass jars. Pour 2 Tbsp dressing into each bottom. Layer: roasted peppers/onions, sliced chicken, halved cherry tomatoes, diced avocado spritzed with lime, and finally 1½ cups chopped romaine pressed gently on top. Seal lids. Refrigerate up to 5 days.
Serve
When hunger strikes, invert onto a large bowl; the dressing cascades down like a fiesta waterfall. Give everything a gentle toss and crunch away. Alternatively, eat straight from the jar if you’re walking to class or commuting.
Expert Tips
Temp your chicken
Pull at 160 °F; carry-over heat takes it to the safe 165 °F while resting. Overcooking equals dry strings that no amount of dressing can revive.
Dry produce = crisp greens
Use a salad spinner until no water drips; excess moisture breeds limp leaves and diluted dressing.
Double the seasoning
Make a quadruple batch and store in an old spice jar. You’ll find yourself sprinkling it on shrimp, scrambled eggs, even popcorn.
Vacuum-seal lids
After sealing, press the center of each lid; if it pops back, air is inside and greens will wilt faster. Use within 3 days instead of 5.
Char under broiler
For deeper roasted flavor, switch oven to broil for the final 2 minutes. Watch like a hawk—peppers turn from perfect to carbon fast.
Pack toppings separately
Crushed tortilla chips, pepitas, or cotija stay crunchy when stored in mini snack clips and added at lunch.
Variations to Try
- Steak Fajita Salad: Swap chicken for flank steak marinated 30 min. Broil 4 min per side, slice thin against grain.
- Low-carb bowl: Skip corn and beans, add diced zucchini roasted alongside the peppers.
- Vegan Power Jars: Use 2 cans of rinsed blackened chickpeas tossed in seasoning and roast 20 min. Replace honey with maple.
- Tex-Mex Caesar twist: Sub creamy cilantro-caesar dressing (blend Greek yogurt, anchovy, lime, and parmesan).
Storage Tips
Refrigerator: Assembled jars keep 5 days when greens are thoroughly dry and sealed. Store dressing at the bottom and greens at the top. If you prefer bowls, layer ingredients in snap-top glass containers with dressing in 2-oz leak-proof cups on the side.
Freezer: Sliced, cooked chicken freezes beautifully for 3 months. Freeze flat in a zip bag, then break off portions for salads, tacos, or soups. Do not freeze the vegetables or lettuce; they become mushy upon thawing.
Reheating: The salad is designed to be enjoyed cold, but if you crave warmth, microwave the chicken and veggie portion 45 seconds, then toss with cool romaine for a hot-cold contrast.
