01 - In a large bowl, combine chicken strips with olive oil, chili powder, cumin, smoked paprika, garlic powder, salt, and black pepper. Toss thoroughly until all pieces are evenly coated with the spice mixture.
02 - Heat a large skillet over medium-high heat. Add the seasoned chicken strips and cook for 5 to 7 minutes, stirring occasionally, until the chicken is cooked through and lightly browned on all sides. Remove from heat and set aside.
03 - In a small mixing bowl, whisk together sour cream, mayonnaise, lime juice, hot sauce (if using), chili powder, garlic powder, salt, and pepper until smooth and well combined. Adjust seasoning to taste.
04 - Heat a dry skillet over medium heat and warm each tortilla for 15 to 20 seconds per side until pliable. Alternatively, microwave tortillas for 15 to 20 seconds wrapped in a damp paper towel.
05 - Lay each warmed tortilla flat on a clean surface. Spread 1 to 2 tablespoons of southwest sauce down the center. Layer with romaine lettuce, cooked chicken, cherry tomatoes, black beans, corn, red onion, and avocado slices.
06 - Fold in both sides of the tortilla, then roll up tightly from the bottom to form a secure wrap. Slice each wrap diagonally in half. Serve immediately or wrap individually in foil for portable meals.
