I like making pizza from scratch. It's super cheap and pretty easy. It's just time consuming because of waiting on the dough to rise.
Most of the time I go with pretty standard toppings (pepperoni, ham, olives, etc) but once in a while I experiment a little.The best one I've come up with was what I called Coney Island pizza.
It was a thicker crust (to mimic a hotdog bun), chili in place of the sauce, cheddar cheese, diced onions, sliced up hot dogs, and a swirl of yellow mustard.
It tasted...pretty much like a chili dog. Not exactly revolutionary, but it's a neat gimmick pizza. I'm kind of surprised I haven't seen any restaurant try something like it yet.
