Slice your rolls in half and top each with ham and cheese and repeat with the turkey and cheese. Build your sandwich and place in 9 x 13 pans. You will have 1 pan of ham sandwiches and 1 pan of turkey sandwiches. Pour the topping you melted in the saucepan evenly over all sandwiches. Refrigerate all day before baking. Bake at 350 for 20-30 minutes or until is cheese in melted. Keep pans covered while baking. Enjoy!
