In a shallow dish combine the cracker crumbs and taco seasoning; set aside. Flatten chicken between 2 sheets of wax paper to ¼ inch thickness. Sprinkle cheese and about 1 tablespoon of chiles on each piece of chicken. Tuck ends of chicken in and roll up; secure with a toothpick. Coat chicken with crumb mixture. Place in a greased 13x9-inch baking dish. Bake uncovered at 350 degrees for 35-40 minutes or until chicken juices run clear. Remove toothpicks.
