Make the most of early summer's longer daylight hours and warm weather with an easy, elegant dinner party cooked almost exclusively on the grill. This Mediterranean-inspired feast is simple enough for a weeknight: toast the evening with a red rhubarb and strawberry cocktail, and snack on bread and pesto while the grill is heating up. Nibble spears of prosciutto-wrapped asparagus straight off the grate; meanwhile, grill the main course of polenta, eggplant, and sea bass wrapped in fig leaves. As the grill cools down, finish with a refreshing slice of strawberry and hazelnut meringue to cap off the perfect night of outdoor dining.
