Are sweet Spanish onions like an apple or blueberries?

Here's why:

* Apples and blueberries are fruits. They grow on trees or bushes and are the edible part of the plant that contains seeds.

* Sweet Spanish onions are vegetables. They are the bulbous roots of a plant, which are edible.

While apples and blueberries have a sweet taste, onions, even sweet varieties, have a distinct flavor profile that is savory and pungent.

It's important to differentiate between fruits and vegetables as they have different nutritional profiles and are used differently in cooking.
