ARTICHOKES

These thorny vegetables may look intimidating to prepare, but at 25 calories each, they're worth the effort. And they're the perfect complement to any meal.

To prepare them, rinse under cold water, chop about an inch off the top, and trim the stem to about a half-inch long. Make sure to watch out for the thorns!
