White button mushrooms are the type most commonly found in stores in the United States. Technically, they are fungi, but are usually thought of as a vegetable for food purposes.

Mushroom caps are handy for stuffing. Raw mushrooms can hold spreads and dips, or they can be baked with other kinds of stuffings, such as seafood or cheeses mixed with herbs and spices.
