According to the Oxford Dictionary: "a tomato is technically the fruit of the tomato plant, but it's used as a vegetable in cooking."
If you ask me, I can't think of tomato as a fruit. It is indeed the fruit or the tomato plant but can't be count as a real fruit like an apple, strawberry or cherry.
We have a garden and grow a lot of delicious tomatoes and use it all year round. I make tomato juice, tomato sauce of all kind and use it during winter period. During summer I love to eat tomatoes as they are and incorporated in vegetable salads. It's my favorite vegetable, there's nothing better than a homegrown organic tomato. So for me tomatoes are vegetables.
