I once had a group of people over for D&D and we opted for a pizza supper. My grandmother and I made the pizzas, and it was a challenge - one person was allergic to cheese, and another loved it, so I ended up making 3 pizzas: one with lots and lots of cheese, one with no cheese but lots of fruit and pepperoni, and one with what I normally used (shrimp, mushrooms, pepperoni, pineapple, mozzarella, and parmesan). BTW: Christmas oranges baked with parmesan cheese is pretty darn tasty!
