Your average cookout burger can weigh in at a hefty 780 calories. If you’re a guest at a summer picnic and looking to save a few calories, you can scoop the bun, halve your patty and top it with guacamole instead of ketchup and cheese. The result is a lean 453 calories. If you’re hosting a cookout, you can take things even further by serving whole-wheat English muffins in place of buns, offering lean 4-ounce patties and swapping standard condiments for healthy grilled veggies. The end result will be only 356 calories—less than half of a standard burger!
