01 - In a large mixing bowl, combine shredded chicken breast with garlic powder, smoked paprika, salt, and black pepper. Mix thoroughly to ensure an even coating.
02 - Add diced avocado, chopped Romaine lettuce, diced tomato, finely diced red onion, cilantro if using, shredded cheese, and ranch dressing to the seasoned chicken. Gently toss all ingredients until evenly coated and well combined.
03 - Arrange the flour tortillas on a clean surface. Spoon the filling mixture equally into the center of each tortilla.
04 - Fold in both sides toward the center, then roll up each tortilla tightly to form a secure burrito.
05 - Heat a large skillet or griddle over medium heat. Lightly brush the surface with olive oil or apply cooking spray.
06 - Place burritos seam-side down onto the skillet. Cook for 2 to 3 minutes per side, turning once, until golden brown and thoroughly heated.
07 - Remove from the skillet, slice each burrito in half, and serve immediately while warm.
