To toast buns - Set the oven control to broil. Put bun halves, cut side up, on a cookie sheet. Put cookie sheet in oven so tops of the buns are 4 to 5 inches from heat. Toast buns about 1 minute or until buns are light brown. Watch carefully! Use the pot holders to take cookie sheet out of oven.
Make Cheesy Cheeseburgers: After you flip the burgers, cook for about 4 minutes, then top each burger with 1 slice of cheese. Cook until cheese is melted.
