The Whopper is one of the original offerings of the fast food restaurant Burger King. It is a customizable menu item, meaning you can choose to add various toppings including cheese, condiments, lettuce, tomatoes, pickles and onions. Ordering a single Whopper without cheese and mayonnaise helps keep the calorie and fat content in check.
