Here is what I do with my extra tomatoes...
I use any tomato, red, yellow, heirloom, cherry, whatever you have.
Line one or two sheet trays with non-stick foil.
Rinse your tomatoes, remove stem end, and cut tomatoes into chunks. Cut cherry tomatoes in half. Place on sheet trays. Take one head of garlic, cut a little off the top to expose garlic, and place in one corner of the sheet tray, that will be nearest the oven door. Drizzle a good olive oil over all, then kosher salt and freshly ground pepper. Mix. Place into a 375° oven and roast until tomatoes are turning brown around the edges and tops. About 40 minutes into this process, check you garlic, if it has softened, remove to cool.
Depending on the type of tomatoes you have, you may get lots of juice. Just be sure they get nice and caramelized. Remove from oven. Working with one sheet tray at a time, and when cool enough to handle, dump the tomatoes, and any remaining juice into a food processor. Squeeze the garlic cloves out of their skins into the food processor. Whiz away until everything is smooth.
I freeze 1 cup portions of this in those Ziplock containers with the blue lids, you can buy at any grocery store. Date the containers. This freezes very well. If your tomatoes were not the really juicy type, you will get tomato paste now and then. The tomato sauce will be thicker than the canned variety. We use it just like tomato sauce for most things....pasta, soups, pizza, cooking a veggie mix, like eggplant, onion, and zucchini. It is richer than the canned, so sometimes, I do use canned instead of my frozen sauce.
The beauty of this recipe is that you DO NOT have to peel the tomatoes and there is no skin visible after putting through the food processor.
