This easy tomato onion sauce is made with just 3 ingredients – onions, tomatoes and olive oil. The onions are cooked until they are tender and sweet, then simmered in the tomatoes. It’s delicious as a pasta sauce, but I also love adding it to many other recipes.
6 lbs tomatoes, peeled, seeded and cored (cut into 4–6 pieces)
3 lbs onions, sliced into half circles
1/4 cup olive oil
salt, ground black pepper, to taste
fresh herbs, for serving (basil, parsley, etc.)
