When I was a child I hated frozen pizza, and even now I still don't like frozen pizza.
Out of the box virtually all of them are pretty sad.
So I buy some of the most primitive and cheapest ones, but use them as a base. Adding my own diced tomatoes and chilis, chopped onions, green and red pepper, black olives, ham, pepperoni...etc.. And cover it in various fresh Italian cheeses.
450 degrees for 12 minutes, then I add the main meats on top for another six minutes. With pepperoni I microwave it for about 15 seconds to get all the grease out before putting it on top for those last six minutes in the oven.
Makes for a decent pizza dinner from frozen pizza I would never eat out of the box.
