The Term Vegetable

The term “vegetable” is a culinary term that generally means any plant part that is cooked and eaten as part of a meal.

However, the exact definition of “vegetable” can vary depending on who you ask. In some cases, the word may be used to refer to any plant-based food, regardless of whether it comes from a fruit, root, stem, leaf, or flower.

Others may define a vegetable as any edible plant part that is not a fruit or seed. This would include mature fruits that are eaten as part of a main meal.

Meanwhile, some people may also consider edible fungi and seaweed to be vegetables, even though they are not technically parts of plants.
