DO YOU HAVE FRESH PESTO AROUND? Do you want to show it off in a fresh, easy pasta dish? This is the one! It really showcases the fresh tastes of summer, with yellow pepper, onion, and all the garlicky goodness of fresh pesto. If you don't have homemade pesto, substitute the best store-bought version you can find. This dish is also rather healthier than many pasta casseroles, with just enough cheese to make it taste rich, but not so much that it overwhelms the clear taste of the pesto. • Serves 6
