In a large mixing bowl stir together, shredded chicken, ham, cream cheese and shredded cheese until well combined.
Place 1/2 cup of the chicken filling on the edge of a flour tortilla, fold over to enclose, and fold in the sides. Roll tightly and place seam side down in a greased baking dish leaving space in between each roll.
Bake at 375 degrees for about 20 minutes or until heated through. Turn half way through the baking time to ensure crispness on all sides.
Once heats, sprinkle with additional shredded cheese if desired and bake an additional 5-8 minutes until cheese is melted. Remove from baking dish and serve.
