While the burgers are cooking, prepare the toppings. You can choose to use whatever toppings you like, but here's what you can do to prepare traditional toppings for the burger:
• Wash the lettuce and tomatoes.
• Halve the burger buns, then thinly slice the tomatoes.
• Place the ketchup and mayonnaise on the table for diners to make their own choice.
Serve. Once the burgers are cooked to each diner's liking, serve the burgers. Place inside the bun with the toppings and deliver to the table.
