Cut chicken into bite-sized pieces and cook in a skillet over medium heat until browned.
Add taco seasoning and 1/4 cup water. Simmer until sauce thickens and chicken is fully cooked.
Warm tortillas in the microwave or on a skillet.
Spread chipotle ranch dressing on each tortilla.
Layer chicken, rice, black beans, corn, avocado, onion, cheese, and cilantro evenly on each wrap.
Drizzle with sour cream and more chipotle ranch if desired.
Fold in the sides and roll up tightly into a burrito.
Optional: Grill each burrito seam-side down in a skillet for 1–2 minutes to seal and crisp.
