I make this cooking sauce in the summer when our tomatoes are abundant and use it all winter. It is a wonderful cooking sauce for chicken, sausage or just to toss with pasta. Especially good with spiral pasta or small penne.
Peel, chop and seed tomatoes in a large pot with onions, garlic and oil. Add herbs, olives, salt and pepper. Bring slowly to a boil and cook gently for 1 hour. Do not burn. Stir in tomato paste and cheese.
Place in canning jars and follow manufacturer's directions for canning or place in freezer containers and freeze. Both work equally well.
