Prep the chicken: If starting from raw, season chicken breast with salt and pepper and roast or sauté until cooked through, then shred.
Leftover or rotisserie chicken works great.
Sauté the veggies: Warm 1 tablespoon olive oil in a skillet over medium heat. Add red onion and bell pepper. Cook 3–4 minutes until slightly softened.
Stir in corn and heat 1–2 minutes.
Build the filling: In a large bowl, combine chicken, sautéed veggies, black beans, Greek yogurt, cheese, chili powder, cumin, smoked paprika, garlic powder, salt, pepper, lime juice, and cilantro. Taste and adjust seasoning.
Warm the tortillas: Briefly heat each tortilla in a dry skillet or the microwave so they’re pliable and won’t crack when rolling.
Assemble: Spoon 1/2 to 3/4 cup of filling across the lower third of a tortilla. Fold the sides inward, then roll up tightly into a burrito-style roll-up.
Repeat with remaining tortillas.
Toast the roll-ups: Lightly oil a nonstick skillet and place roll-ups seam-side down over medium heat. Cook 2–3 minutes per side until golden and warmed through, with the cheese melted.
Serve: Slice in half and serve with extra lime wedges, salsa, or a dollop of Greek yogurt. Add avocado or hot sauce if you like more richness or heat.
