Just used some of these last night, not on a pizza but as an ingredient in a sauce that I made. They are a Heinz foodservice product which I picked up in a restaurant supply outlet. Very similar to 6 in 1's and Classico's which are also Heinz products. Ingredient list reads: vine-ripened whole unpeeled ground tomatoes, tomato puree, salt and citric acid. FYI, I'd but them again!
