You love burgers, but you're watching your waistline. That doesn't mean you have to resort to eating a dry patty of meat. Sure, you'll want to ditch the cheese and the mayo. Think about it. Just one slice of cheese has about 70 calories and 6 grams of fat while a tablespoon of mayo has 110 calories and 11 grams of fat. Of course, there are ways to trim the fat without trimming the taste. You can still enjoy a burger that packs a mean punch without overdoing it. Dress up your burger with healthy extras. Lettuce, pickles, tomato, avocado, salsa, mustard and ketchup are all acceptable toppings that won't tack on a ton of fat and calories.
