Hamburger

A hamburger is a popular type of sandwich! It is made with a bun (a round piece of bread), two pieces of cooked ground beef (which is also sometimes referred to as a "patty"), lettuce, tomato, and sometimes cheese and other toppings like ketchup and mustard. You can order one at many restaurants, or you can make one at home using a frying pan and some ingredients from the store. To make a hamburger, you need to take the cooked ground beef, add it to a bun, and top it with any of your favorite toppings! Enjoy your delicious hamburger!
