Now that the holidays have come and gone, chances are you're craving simple, healthful suppers that are short on fuss and expense but still have flavor and flair. The solution? Fill your cupboard with barley, bulgur, Israeli couscous, and quinoa. These quick-cooking grains are readily available in most supermarkets, hold up well when combined with other ingredients, and offer a tasty alternative to rice or pasta. Once you get the hang of using them, mix and match the grains with your favorite vegetables, spices, dried fruits, and nuts. Soon you'll be creating your own quick recipes that'll keep weeknight meals interesting without piling on the calories, putting the squeeze on your wallet, or eating into your postfestivity downtime.
