Asparagus is a perennial vegetable that originated along the Mediterranean coast. It is a member of the lily family with green stems that function as leaves and reduced true leaves. Historically, Romans used the phrase "do it in the time it takes to cook asparagus" to refer to something being done quickly, as asparagus cooks very fast. Asparagus should be selected based on firm spears with closed tips and stored refrigerated for no more than three days. It can be boiled, microwaved, or stir-fried and is nutritious, containing vitamins A and C as well as fiber and iron.
