This dish is very versatile! It can be made with ham, chicken, turkey or even ground beef. I have made all of these combos and they all taste GREAT! You can also switch up which cheese you use depending on your taste. For example, I use colby-jack for this casserole when I make it with ground beef/venison but I love grated parmesan when I make it with chicken or turkey. Give it a try and don’t be afraid to use up those leftovers.
