I use the Centos too. I've been able to find them the cheapest at Fairway Market - 2 cans/$6. I add about a teaspoon or less of oregano, salt to taste, 2 tbspn red wine vinegar and 1 tbspn EVOO. I use the stick blender to purée the whole tomatoes because I don't care for texture of hand crushing them, but its all a matter of preference. I don't cook my pizza sauce, because I feel it cooks just enough on the pizza. Mine take 6 minutes in the regular oven. If I had a WFO, I probably would cook it a little since the pizzas aren't in there long.
