Tender marinated chicken sears hot while bell peppers and onions pick up just enough char to smell like the grill. Expect a bright lime-garlic backbone, gentle chili warmth, and tortillas you can load at the table.

Instructions
Make the marinade: In a medium bowl, whisk 2 tbsp olive oil, lime juice, garlic, jalapeño, chili powder, cumin, smoked paprika (if using), 1/2 tsp salt, and black pepper. Taste—it should be bright and a little salty so it seasons the meat.
Marinate the chicken: Slice chicken into 1/2-inch (1.3 cm) strips against the grain. Add to the bowl and toss to coat. Cover and refrigerate 30 minutes to 2 hours.
Prep the vegetables: While the chicken rests, slice the onion and peppers into even strips. Toss with 1 tbsp olive oil and the remaining 1/2 tsp salt.
Heat the pan hard: Set a 12-inch cast-iron skillet over medium-high to high heat until it’s just starting to smoke, 3–5 minutes.
Sear the chicken in batches: Add half the chicken in a single layer. Cook 2–3 minutes until browned on the first side, flip, and cook 1–2 minutes more until the thickest piece hits 165°F/74°C. Transfer to a plate and repeat with the rest. Don’t pour excess marinade into the pan; it will steam.
Char the vegetables: Return skillet to high heat. If dry, add a teaspoon of oil. Add onions and peppers. Cook, tossing occasionally, until tender-crisp with charred edges, 5–7 minutes. Scrape up browned bits from the pan.
Combine and moisten: Return chicken (and any juices) to the skillet, toss with vegetables 30–60 seconds to mingle flavors, then cut heat. Squeeze another wedge or two of lime over the top.
Warm the tortillas: Pass tortillas over a low open flame with tongs 5–10 seconds per side until pliable and speckled, or wrap in foil and warm in a 300°F/150°C oven for 5–10 minutes. Keep wrapped to hold heat.
Serve: Transfer the sizzling mix to the table, set out tortillas and toppings, and let everyone build.
