Stuffed Pizza Muffins- these are awesome! I use shredded mozzarella rather than chunks of string cheese. How in the hell would you neatly roll THOSE up? Also, we call them pizza rolls b/c pizza cupcakes sounds stupid and revolting.
"cupcake" ham and eggs! Use silicone muffin molds to put the ham, then add in onion , sliced mushrooms, cheese or ingredient that suits you best and an egg on top . Put it in the oven and when it serves have this original appetizer.
