Pizza is usually,
dough - can be fresh or store-bought
pizza sauce - can be fresh or from a can or jar
I don't have pictures but the sauce was leftover fresh sauce -
boil up a jar of canned tomatoes(San Marzano, Italy region are the best), a scoop of tomato paste if you have, garlic, a spoonful of sugar if needed to reduce the acid, salt, pepper, onions, spices, etc.
cheese - usually mozzarella but can be any kind you like
toppings - anything edible
I had some onions, a piece of tomato, sausage, and mushrooms to use.
and you need one Fn
hot oven to bake your pizza - you could have a baking stone but I just baked mine on a greased cookie pan.
CAUTION: If you can't stand the heat, get out of the kitchen.
