Preheat oven to 400 degrees F. Spray a large baking sheet with nonstick cooking spray; set aside.
In a large mixing bowl, combine cooked chicken, salsa verde, cheese, chili powder, cumin, paprika, oregano, garlic powder, salt and pepper.
Wrap the tortillas in a slightly damp paper towel and microwave 6 at a time for 30 seconds to make them easier to fold.
Scoop a heaping 1⁄4 cup (approx. 38 grams) of chicken filling onto one half of each tortilla, fold in half and place on prepared baking sheet and gently press down to hold shape.
Bake for 8-10 minutes, or until heated through and cheese has melted. Turn oven to high broil and cook for an additional 1-2 minutes or until tortillas are golden brown.
