Walnuts and Gorgonzola cheese are a winning combination in this hearty pasta dish, ready in about 15 minutes. The hot pasta warms the sauce to the perfect eating temperature, making for less cooking. This dish is also great at room temperature or cool, if you like a pasta-salad type option for al fresco dining on summer nights. Serve this dish with some grilled chicken on top for a main dish salad or on the side of grilled pork tenderloin or sliced flank steak and some steamed broccoli. If you have blue cheese on hand, it is a suitable substitute for the gorgonzola.
