http://www.huffingtonpost.com/kurt-friese/why-the-modern-tomato-is_b_868318.html Yes, the tomato is technically a fruit, not a vegetable, but for purposes of economics the USDA classifies it as a vegetable, and as such it is the second most popular vegetable in the nation after that other burger staple, lettuce. This is surprising in only one respect: A vast majority of the tomatoes consumed in the U.S. every year ($5 billion worth), are devoid of the flavor and nutritive value they once had.
