Don't knock homemade pizza's. Make your own dough using good quality flour etc, let it rise then knock the air out and roll into pizzaish shapes. You can make your own tomato paste by reducing down a few cans of plum tomatoes plus some herbs and seasoning (and a chilli or two if you like it hot). Get a selection of salami's sliced from the deli, some mozarella and any veg you might want.
Get oven as hot as possible and put the pizza's in as soon as they have been assembled. (I found the gas BBQ on full whack worked well as it gets up to about 350deg C).
Delicious.
