What are your favorite dishes and recipes using tomatoes?

I saw some lovely tomatoes in the store today, but I didn’t buy any because we already had quite a few in the house already.

I made some lasagna today using some very tasty marinara sauce and was thinking that it might be fun to make some homemade sauce.

Do you guys have any favorite tomato (sauce or otherwise) recipes? Maybe some soup, salsa, or even a tart would be nice.
