Lots of Sharp Cheddar, Ritz, Get creative
My dad has always meatballs for spaghetti and meatballs with a chunk of cheddar in the middle... I would think you could do that and add cracker crumbs to the mixture instead of bread crumbs. Same thing with meatloaf.
I make stuffed mushrooms with herb cream cheese in the middle and top them with cracker crumbs before I bake them. You could add cheddar to the mix.
