I seem to buy tomatoes and then forget to use them before they are to the point I don't want to eat them raw. So, I started throwing them in the freezer so when I collected enough, I would make some tomato sauce.
Today, I had so many in my freezer that they were starting to fall out so into a pan they went with olive oil.
Add onion, fresh basil, garlic, salt, pepper & some parsley.
Cook until soft, send through food processor and return to pan to and simmer to reduce.
You get a really nice, thick sauce.
