Confit a bunch. Make some garlic confit while you’re at it. That stuff, especially on some decent bread, is ridiculous.

Make buttloads of “base sauce” (you can then easily turn it into pizza/pasta sauce or whatever just by adding things) or just passata.

Soups, stews, curries.

Good tomatoes work pretty well as a “sandwich topping”, bit of mayo, salt and pepper is all you need.
