Today I told myself I'd order something new, but in the end I went with my old standby:
Fried eggplant, spinach, minced garlic, roasted red peppers and ricotta.
Another one I'm fond of, (but rarely get) is bacon, pineapple and green peppers.
If I'm making pizza, then it's usually salami/hot sausage, mushroom, onions and peppers with some chili peppers or even pepperoncini and/or margherita (but only if I can get really good, fresh mozzarella and basil or good quality dried oregano).
