Why it's good: Bean tortillas are high in protein and folic acid and also provide calcium, phosphorous, iron, and zinc. To make this snack even lower in fat, you can substitute a whole-grain tortilla, fat-free refried beans, and a soy-based, fat-free cheese substitute.
When it's good: As a substantive, post-run snack or light meal.
Calories: 310 per 8-ounce flour tortilla, 2 tablespoons salsa, 1-ounce part-skim mozzarella cheese and 1?2 cup refried beans.
