There are some fruits that people always mistake for vegetables because, well, they just seem more like vegetables. They’re often more savory than sweet and are used the way vegetables would be used, say in salads or other vegetable dishes.
Fruits always contain seeds and pits, which is what makes all of the foods listed below fruits rather than vegetables.
Tomatoes are a fruit in the nightshade (Solanaceae) family.
