Preheat the oven to 425°F. Lightly grease a large baking sheet with olive oil or nonstick cooking spray, and set it aside.
In a large bowl, combine the chicken, bell peppers, onions, olive oil, white wine vinegar, chili powder, salt, onion powder, garlic powder, cumin, smoked paprika, and black pepper.
Toss the ingredients together until everything is well combined and evenly coated.
Transfer the mixture to the prepared baking sheet and spread it into an even layer to ensure even cooking.
Place the baking sheet in the oven and bake for 20-25 minutes or until the chicken is fully cooked.
Remove from the oven, then mix in the lime juice and cilantro.
Serve immediately in warm corn tortillas, flour tortillas, or with Mexican sides.

Notes
Chicken: Boneless skinless chicken thighs also work great. Slice them into even strips.
Onion: White or yellow also work.
Vinegar: Apple cider vinegar or lime juice also works.
Use two pans if needed. If your peppers and onions are on the larger side, don’t crowd everything onto one baking sheet - spread it out over two pans so everything roasts instead of steams.
Storage, reheating, and freezing: Leftovers will keep in the fridge for up to 5 days in an airtight container. Reheat in the microwave or in a skillet over medium heat until warmed through. To freeze, let everything cool, then store in a freezer-safe container or bag for up to 3 months. Thaw in the fridge overnight before reheating.
