I made this with a sourdough pizza crust with a mature soudough starter... I started out with tomato paste then I had pepperoni,leftover hamburger from the night before and bacon on hand so it ended up in the pizza...I added bell pepper and white onion.I used marble cheese and a little parmesan to top it off. It turned out soo good!
Combine 1 cup fresh starter, 1/2 cup warm water, 1/4 cup (olive) oil,
2 tablespoons sugar, 1/2 teaspoon salt. Stir in 2 to 3 cups flour,
or enough to form a stiff dough. Knead until smooth. Let rise
until doubled. Roll out or gently shape with hands until about 14"
across and about 1/4 inch thick. Place on a greased and floured 14"
pizza pan (or you can shape it to fit a rectangular jelly-roll
pan). Let stand about 1 hour. Prepare the sauce by combining one
7 or 8 oz. can tomato sauce, 1 crushed clove of garlic, 1 teaspoon
crushed dried oregano leaves, 1 teaspoon crushed dried basil
leaves, (1/4 teaspoon ground fennel). Preheat oven to 425. Just
before baking, spread sauce on dough, cover with desired toppings
(1/4 lb. sliced mushrooms, 1/4 lb. cooked sausage, sliced salami, etc.,
1/4 to 1/2 lb. grated mozzarella, sliced olives, sliced peppers, etc.).
Sprinkle top with grated parmesan and/or romano cheese and a few
dried parsley flakes. Bake 20 to 25 minutes, until done.
