Yes, tomatoes are fruits. Apparently. Well, actually, it depends where you're sitting on the Venn diagram. There are botanical fruits, and culinary vegetables. Things like tomatoes sit in the middle. We eat it as if it were a vegetable, yet it's classed as a fruit.
Scientifically speaking, a tomato is definitely a fruit. True fruits are developed from the ovary in the base of the flower, and contain the seeds of the plant (though cultivated forms may be seedless). Blueberries, raspberries, and oranges are true fruits, and so are many kinds of nut.
However you define them, we picked them, washed them, and ate them.
With a lot of cheese, and some wine and olives.
