Dip each tortilla in sauce. Place a large spoonful of chicken, sauce and cheese in the center of each tortilla. Roll up and place in ungreased baking pan. Pour remaining sauce over all. Sprinkle remaining cheese on top. Bake at 350 degrees for about 25-30 minutes or until cheese is slightly browned.
