5/26/2011 – No doubt, grilling out is a favorite American pastime. But can you guess what our #1 favorite item to grill is? The hamburger, of course, says an overwhelming 85 percent of people polled by the Hearth Patio and Barbecue Association. Americans love tomatoes on their burgers. A hamburger without a slice of fresh tomato is like a meatball without the marinara. You don’t want to go there – the tomato is what makes the sandwich. Plus, fresh tomatoes are high in vitamin C and a good source of vitamin A, fat-free, low in sodium and contain the antioxidant lycopene.
