Use pasta as a base for healthful dishes rich in veggies, lean proteins and healthy fats. Light coat whole-wheat spaghetti with olive oil, then mix in wilted greens and chopped hazelnuts for a decadent but healthful and easy-to-prepare meal. Top pasta with roasted veggies -- including fennel, red peppers, onions and garlic -- and then it with tomato sauce and basil. Alternatively, incorporate pasta into cold salads. Whole-wheat rotini pairs well with chopped kalamata olives, roasted red peppers and a lemon juice vinaigrette, while bowties, steamed shrimp, red bell pepper and red pepper flake-infused olive oil mix for a fiery salad option.
