This tart is wonderful picnic, potluck or party food--it's great served warm, cold or at room temperature! Simple and very tasty, I often make this tart when fresh zucchini are in season. For ease of preparation, I've used a crescent roll crust, but you may use a regular shortcrust pastry if you wish. You will need a 9 or 10-inch tart tin with a removable bottom. P.S. If you don't have a tart or quiche pan, just use a 9 x 13-inch baking dish.
