Summery Cucuzza with Basil and Tomato

A mild mélange of fleshy leaves, crunchy squash bits, and fresh tomato dice brightens grilled chicken or fish steaks. Or make a meal in a bowl: Spoon the moist mixture over ricotta-filled ravioli or a soft cheese-laced polenta to act as sauce and vegetable. However you present the dish, add the tomatoes just before you serve it, or they will lose their plump vigor and turn the sauce watery.
