This colorful beef fajita contains fresh cilantro, yellow bell peppers, and red onions. Sour cream and a squeeze of lime juice give it a cool taste. The longer the flank steak marinates, the more flavorful it will be. You can substitute 1 1/2 pounds of boneless, skinless chicken breast for the beef, if you wish.
Called a supergrain, quinoa dates back to the Incan civilization. It has more protein than most grains (5 grams per serving) and is gluten- and wheat-free. If you prefer, you can replace the water-cress with fresh baby spinach leaves.
