Step 1: Marinate and Grill the Chicken

• In a bowl, mix olive oil, lime juice, chipotle chili powder, garlic powder, onion powder, smoked paprika, cumin, salt, and black pepper to create a marinade.
• Coat the chicken breasts evenly and let them marinate for at least 15 minutes (or up to 2 hours for deeper flavor).
• Heat a grill or stovetop pan over medium-high heat.
• Grill the chicken for about 6-7 minutes per side, or until the internal temperature reaches 165°F (75°C).
• Remove from heat, let rest for 5 minutes, then slice into thin strips.

Step 2: Make the Chipotle Ranch Sauce

• In a small bowl, whisk together mayonnaise, sour cream, buttermilk, lime juice, minced chipotle peppers, adobo sauce, garlic powder, onion powder, dried dill, and salt.
• Adjust seasoning to taste and refrigerate until ready to use.

Step 3: Prepare the Cilantro-Lime Rice

• Cook white or brown rice according to package instructions.
• Once cooked, stir in chopped cilantro, lime juice, and a pinch of salt.

Step 4: Assemble the Burritos

• Lay a large flour tortilla on a clean surface.
• Spread ¼ of the rice, black beans, grilled chicken, shredded cheese, lettuce, tomatoes, red onions, and cilantro in the center.
• Drizzle with chipotle ranch sauce.

Step 5: Grill the Burritos

• Fold in the sides of the tortilla and roll tightly into a burrito.
• Heat a skillet over medium heat and lightly grease with oil.
• Place the burrito seam-side down and grill for 2-3 minutes per side until golden brown and crispy.
