Laura, my son is in SF, so I know hwere you're coming from and I think I can help you out. Living on the South Side, I know what you mean. Simplest recipe is as follows:
3 cups flour
1 cup warm water
2 tsp yeast ( 1 Pkg)
1 tsp sugar
1 tsp salt
3 Tblsp oil
Mix yeast with water and sugar...let settle for 5 minutes. Add oil. Mix salt with flour and add to yeast mixture...knead for 5 minutes, until it forms a nice ball. Put in warm place to rise for at least 1 hour. Divide into two balls.
Sauce: There's all kinds of thoughts on this one, but the simplest is to get a large can of crushed tomatoes, add a little Basil, oregano, garlic powder,sugar, to taste. Simmer for about twenty minutes...let cool.
I take two pizza pans...whatever size you have. Butter them or spray with oil...sprinkle with corn meal. Roll out the dough, place on top, cut off excess. Spread sauce, add whatever toppings you want, top with motzarella, perhaps a little oregano and cook in a pre-heated oven at 500 degrees for 8 minutes, turning once during the process. Make sure the oven is pre-heated to this temp and watch it.
This is over-simplification of the process, but coming from the South Side, the results should be good for our tastes. All the best to you and yours.
