You may only know tahini for adding a toasty flavor to hummus, but it deserves star billing. Two tablespoons contain 6 grams of protein and 12 percent of your daily value of calcium. Try it in a zesty salad dressing: Combine 2 T. tahini, 3 T. lemon juice, 1 T. water, 1/2 t. salt and 1 small clove garlic.
