Hi !
I can't see your picture, so I don't know how much is too much. If you go with a salad, that's maybe 1/2 tomatoes per person per meal. So, to use them more effectively, I'd indeed put them in a sauce (or several).
Four about 2 person's worth of sauce, I go with
8 oz of cream cheese, olive oil, salt, pepper, and 6 to 7 tomatoes, and either garlic, herbs or oinions.
You can also cook a batch of several sauces and freeze them. There are also some recipes, such as osso bucco that require to stew in a tomato sauce. With
this recipe for example, you can replace the can tomatoes with about 10 to 12 tomatoes (for 6 persons, but you can freeze the rest).
Edit:I don't know how to write properly
