I'm just going to try and get through the last few super-summery tomato suggestions, ok?
Make a tomato & avocado salad. Slice up tomatoes & avocados; mix together with shredded basil, salt, and freshly ground pepper.
I ate my salad plain, since it already featured an entire small avocado, but you can drizzle on some olive oil or vinaigrette if you really want to.
I actually really wish it were fall, and that I could then eat the fall food to match. But we live in California, and thus there is never a fall. It's so frustrating.
