I have IBS and therefore am not supposed to eat red meat, dairy products, etc., but sometimes I have to work with what I have and what I can afford. I was really craving pizza last night so I created this recipe for myself and my bf. We sometimes try to splurge and he gets his real pepperoni and real cheese on his pizza and I get my substitutions, but this time, I couldn't afford it, nor could I afford ordering out, so I just made them partly homemade and he said he really liked them. The first variation is made with plain English Muffins. The second is made with Extra Sourdough bread. We've actually already had the muffin pizzas twice this week, and I had the second variation last night because we were out of muffins. I used Extra Sourdough bread because it needed to be used up before it went bad, but regular Sourdough bread should work just as well. French bread should also work just fine, as a variation, but I have only included two. Of course, add any additional toppings you prefer or change the amounts or cooking time to your tastes. I was just really going for a simple pizza. Mine was pepperoni and pineapple, the bf's was pepperoni only. Edited to add an update to this: Bf and I have been using a baking rack on top of the foil-lined baking sheet, which allows the bottoms to get crispy too. We have used french bread, english muffins, and sourdough bread very successfully, as well as having successful results using real cheese, regular pepperoni, etc. (for bf, since he doesn't have IBS).
