Whisk together minced chipotle peppers, garlic powder, onion powder, and salt in a bowl.
Coat chicken strips in the chipotle mixture and marinate for 10 minutes.
Heat a non-stick grill pan over medium-high heat and cook chicken for 6-8 minutes until internal temperature reaches 165 degrees Fahrenheit.
In a small bowl, combine Greek yogurt, ranch seasoning, and lime juice to create the chipotle ranch dressing.
Lay out tortillas and distribute cooked brown rice, black beans, grilled chicken, and shredded cheese evenly across them.
Drizzle the chipotle ranch dressing over the fillings and top with shredded lettuce.
Fold the sides of the tortillas inward and roll tightly to seal the burritos.
Optional: Sear the assembled burritos in a dry skillet for 1 minute per side until the exterior is crisp and golden.
