Don't let tomatoes go to waste at the end of the growing season if you don't have time to put them up. Just wash them and freeze them in bags--cutting large ones into quareters--until you are ready to use them. The night before making a sauce or soup, transfer the bags to the fridge. The next morning, just put the tomatoes on a baking sheet and let them thaw to room temperature--after about an hour the skins will slip off.
Then use the tomatoes to make your favorite tomato sauce or soup.
I have not tried this but it sounds like something that would work..if you have the room to store the tomatoes in the freezer.
