2-4 ounces cheese, depending on the size of your sandwich, sliced thin
1-2 tsp mayonnaise, depending on the size of your sandwich
Instructions
Heat a skillet over medium heat.
Spread one side of both pieces of bread with mayonnaise - just enough to coat the surface or each with a thin layer. Lay one slice of bread in the hot skillet, mayonnaise side down. Layer the sliced cheese over the bread then top with the second slice of bread, mayonnaise side up. Turn the heat down to medium-low.
When the cheese looks about halfway melted, use a spatula to flip the sandwich over in the pan. Use the spatula to press the sandwich down slightly. Let cook for a couple of minutes, then peak underneath. If the bread is getting too brown, flip the sandwich back over. Continue flipping back and forth every 30 seconds or so to let the cheese melt fully without burning the outside of the bread.
