Preheat oven to 400 degrees and line a baking sheet with non-stick foil.
Heat a skillet over medium to high heat and warm each tortilla for about 10 – 15 seconds each side.
Once warmed, fill the center of each tortilla with about 1/2 cup of chicken, 1/4 cup of avocado, 1/4 cup of cheese, 1 tablespoon of sour cream, and 1 tablespoon of cilantro.
Roll into a burrito (flip/tuck in the ends of the burrito and fold the other sides of the burrito on top of each other).
Place seam side down onto foil-lined baking sheet and bake for 12 – 15 minutes, or until the tops of the burritos are golden brown.
Serve with additional cilantro, sour cream, avocado, and/or salsa.
