Here is my basic no-cook tomato sauce for 2-3:
1 15-oz. can Hunt's tomato sauce
2 tbsp. extra-virgin olive oil
1 clove fresh garlic, very finely minced
several shredded fresh basil leaves
Make ahead, allow to stand at least two hours. Do not substitute other brands of tomato sauce (no, I am not being paid to say this; somehow I don't think ConAgra needs my endorsement). Do not use pre-peeled or pre-minced garlic (ever). Do not use dried basil. I use Goya olive oil- good price/quality ratio. Do not add salt.
Variations:
Take out basil, subtitute flat-leaf parsley. Add small can good tuna, freshly-ground black pepper.
or,
Add small amounts of your own fresh herbs, finely minced.
