I've been making my own tomato soup since having too large a crop of tomatoes a couple years ago. I actually call mine TV soup as I add carrots, onions, red peppers, celery, whatever I can find in the freezer that needs to be used up. Then I puree all of it so you really can't tell what's in the soup. Still tastes like tomato soup as it's mostly tomatoes from the garden but you're getting a little added vitamins from the rest of the veggies. The folks I've offered my pints of soup seem to like it so I must be doing something right. I just hate to see anything go to waste and when my neighbors were hiding from me when they saw me coming with a basket full of veggies at the end of the summer, I had to do somethng with them.
I also dehydrate cherry tomatoes for those recipes calling for sun dried tomatoes. I don't keep them in olive oil but in a canning jar in the pantry. I also dry the larger tomatoes and then pulverize them into almost a powder to put them into tomato sauces that are a bit too wet. This powder sucks up the excess moisture plus gives it a punch more of tomato flavor.
