Summer entertaining can be light and breezy — or you can end up hosting a multicourse event that has you wishing you were just lounging alone in your backyard. Keep things nice and easy by forming a game plan and prepping ahead of guests' arrival. This grilled pizza bar is the perfect solution: The pizza shells can be partially grilled and then frozen, and the three sauces can be thrown together the night before. Invite guests to top their own pizzas with a variety of produce, meats, cheeses and sauces, and then finish their creations on the grill. This way, you can spend more time mingling in the sunshine, and less time trapped in the kitchen.
