01 - Preheat the oven to 400°F and lightly grease a baking dish.
02 - In a small bowl, combine the chili powder, smoked paprika, cumin, garlic powder, onion powder, salt, and pepper.
03 - Place each chicken breast between two sheets of plastic wrap and pound to an even thickness of about 1/2 inch.
04 - Drizzle the chicken with 1 tablespoon of olive oil and sprinkle half of the spice mix evenly over both sides.
05 - Heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Sauté the sliced peppers and onions until just tender, about 3–4 minutes. Remove from heat and toss with the remaining spice mix.
06 - Lay the seasoned chicken flat. Top each breast with an even layer of the sautéed vegetables and a sprinkle of cheese.
07 - Roll up the chicken tightly and secure each roll with toothpicks. Place them seam-side down in the prepared baking dish.
08 - Bake for 25–30 minutes, or until the chicken is cooked through and juices run clear.
09 - Let the chicken rest for 5 minutes. Remove the toothpicks, slice the rolls, and serve garnished with cilantro and lime wedges if desired.
