What vegetables are brown?

There are a few vegetables that are brown, but they are not as common as other colors. Here are some examples:

Naturally Brown:

* Mushrooms: Many types of mushrooms have a brown cap and stem.

* Chestnuts: These nuts are technically a fruit, but often considered a vegetable in cooking. They are brown with a shiny, leathery skin.

* Jerusalem Artichokes: These root vegetables have a brown, knobby exterior.

* Brown Lentils: These lentils are brown with a slightly reddish hue.

* Beetroot: While the root is typically red, sometimes it can have a brown or black color.

Browned:

* Caramelized Onions: Onions that are cooked until they turn brown.

* Roasted Vegetables: Many vegetables, like sweet potatoes and carrots, can be roasted to a brown color.

Important Note: Some vegetables, like potatoes, can turn brown after being peeled or cut due to oxidation. This is usually not harmful, but can affect the appearance of the vegetable.
