Preheat a large skillet or grill pan over medium heat, adding olive oil until shimmering.

In a mixing bowl, combine cooked chicken, mozzarella, cheddar, cream cheese, garlic, parsley, salt, and pepper.

Lay a tortilla flat, spoon the cheesy chicken mixture into the center, and roll tightly.

Place wrapped tortillas seam side down in the skillet, cooking for 2-3 minutes on each side until golden brown.

Remove from skillet, slice in half diagonally, and serve immediately with additional parsley if desired.
