When I'm entertaining in the summer, I like to keep things simple and cool (i.e. I try to avoid turning on the oven for fear that my guests will melt before we sit down to eat). These simple avocado boats stuffed with mozzarella and tomato fit the bill, can be served as an appetizer or a side dish and can be made in about 5 minutes. Serve with a dinner made on the grill to keep guests (and you) out of the kitchen and enjoying the sunshine! Ingredients (serves 4): 2 avocados
