What can be done with an overabundance of grape tomatoes?

I have grape tomatoes coming out of my ears. My kids won’t eat them, and my husband is working out of town for the next couple of months. I gave quite a lot of them away, but still have much more than I’ll be able to eat before they go bad.

Are they good to use for tomato sauce? Are they easy to can? I’ve done some canning in the past, but never tomatoes. All practial ideas and advice will be much appreciated!
