These flavorful, spicy greens come form the same plant that makes mustard seed (which is commonly ground to make the popular condiment). Mustard leaves can be flat, crumpled or lacy-edged, and can take on a number of colors.

One of the most pungent and interesting of all the greens, as well as a very generous source of vitamin A, mustard greens are widely used in French, Chinese and Southern U.S. cuisines.
