Make the most of a small food budget by building a meal around nutrient-rich superfoods. Sweet potatoes and bell peppers are not only naturally delicious, they're also packed with vitamins, minerals and cancer-fighting antioxidants. Chop sweet potatoes and peppers into cubes and fry them as you boil your favorite pasta. Add the cooked pasta to the pan and mix in extra veggies if desired. Flavor with hot sauce, salt and pepper or your favorite herbs. Sprinkle the dish with Parmesan cheese to complement the natural flavors of this richly colored dish.
