Cheeseburgers can include variations in structure, ingredients and composition. As with other hamburgers, a cheeseburger may include various condiments and other toppings such as lettuce, tomato, onion, pickles, bacon, avocado, mushrooms, mayonnaise, ketchup, and mustard.

Single Cheeseburgers: 600 g / 1.2 lb beef mince (ground beef) , at least 20% fat (Note 1 for quality)

So what's the right way? Bottom bun, ketchup and mustard, pickles, patty, cheese (if that's the way you roll, otherwise put it underneath the patty and keep your burger right side up), tomato, lettuce, onion, mayo, top bun.
