Marinate the chicken. In a bowl, combine 1 tablespoon olive oil, minced chipotles, adobo sauce, garlic, cumin, smoked paprika, oregano, lime zest, lime juice, salt, and pepper. Toss in the chicken.
Let it sit 15–30 minutes (or up to 8 hours in the fridge).
Make the yogurt sauce. Stir Greek yogurt with adobo sauce, lime juice, and salt. Adjust heat to your taste. Chill until serving.
Prep the fillings. Warm the rice.
Rinse and drain black beans. Slice veggies and chop cilantro. If using frozen corn, thaw it; if fresh, give it a quick sear in a dry skillet for char.
Cook the chicken. Heat 1 tablespoon olive oil in a large skillet over medium-high.
Add chicken in a single layer. Cook 5–7 minutes, stirring once or twice, until browned and cooked through. Taste and adjust salt.
Warm the tortillas. Heat tortillas in a dry skillet for 20–30 seconds per side or wrap them in a damp towel and microwave for 20–30 seconds. Warm tortillas are less likely to tear.
Assemble the burritos. Lay out a tortilla.
Spread a spoonful of yogurt sauce. Add 1/4 of the rice, beans, corn, chicken, tomatoes, onion, avocado, lettuce, and cilantro. Don’t overfill; leave 1–2 inches at the edges.
Fold and roll. Fold the sides in, then roll from the bottom up, keeping it tight. Place seam-side down.
Repeat with remaining tortillas.
Optional crisp. For a toasty exterior, place rolled burritos seam-side down in a hot skillet for 1–2 minutes per side until lightly browned.
Serve. Slice in half, drizzle with extra sauce, and add hot sauce if you like more heat.
