In a mixing bowl, whisk together Greek yogurt, mayonnaise, ranch seasoning mix, lime juice, garlic, and cilantro until smooth and creamy. Chill while prepping other ingredients.
Warm cooked chicken in a skillet with taco seasoning. If starting from raw, cook fully until internal temperature reaches 165°F, then shred or dice. Season as needed.
Slice avocados and toss with lime juice to prevent browning.
Warm tortillas in a skillet or microwave until pliable to prevent tearing.
On each warm tortilla, spread 2 tablespoons ranch sauce down the center.
Layer with chicken, avocado, mozzarella, red onion, and cilantro. Add a squeeze of lime juice if desired.
Roll up each burrito, tucking in sides first, then rolling tightly from bottom.
Toast seam-side down in a dry skillet for 2-3 minutes until golden and cheese melts inside.
Cut burritos in half diagonally and serve with extra ranch sauce and lime wedges.
Notes
Use slightly firm avocados for easier slicing. Very ripe avocados can be mashed and spread instead.
Chicken thighs have more flavor than breasts. Rotisserie chicken works perfectly for this quick recipe.
Warm tortillas properly to prevent tearing when rolling. Don’t overfill burritos for easier wrapping.
Extra ranch sauce works great as salad dressing or dip for chips.
Stored burritos may have slight avocado browning, but taste remains delicious.
