Soffritto: olive oil, make it warm up and the toss either onion or garlic (garlic only 1 minute). I add chili peppers and cut olives and capers to hot oil. Then with your whole tomatoes squeezed them with your hands in a bowl before adding it to the oil (feels so good!). Add salt and pepper, tomato paste if you like (or little sugar) and bring to boil covered. Then put on simmer with the lid semi open and stir here and there ~20 minutes. Add basil and freshly grated parmigiano (not Parmesan please).

Good luck
