I usually only have excess of the 'Juliet' grape tomatoes, and there are often too many. I quarter them then roast in the convection toaster oven at 325deg. for about 20min. Then freeze. They are very tasty this way and not so mushy as they can be if you freeze them raw. I use them on fritattas and add to pizza or bruschetta all summer. You can do this with other tomatoes too, but juicier ones take longer to roast - you need to get rid of a lot of the moisture out of them.
