What vegetable is really a fruit but people think its vegetable?

This is a classic trick question! The answer is tomato.

While we typically use tomatoes in savory dishes and consider them vegetables, botanically speaking, they are fruits. This is because they develop from the flower of the plant and contain seeds.

The confusion arises because of how we use them in cooking. We often eat them raw or cooked in savory dishes, which leads us to categorize them as vegetables.
