Place the toaster on its side, so that the slots are stacked one on top of the other.
Top one slice of bread with cheese. Make sure the cheese is contained within the crust of the bread, and not sticking out. Place inside the bottom slot of the toaster, ensuring the bread is pushed all the way to the back.
Place the other slice of bread into the top slot of the toaster, pushing it all the way to the back.
Push the lever to turn the toaster on. Watch the cheese melt and your bread get nice and toasty (approximately 1-1 1/2 minutes). Once they pop out, smush together. Enjoy!
