One ingredient makes all the difference when it comes to mind-blowing grilled cheese.
2 slices bread
1/2 cup mayonnaise
4 slices sharp cheddar
Spread a layer of mayonnaise on one side of each piece of bread.
Transfer bread, mayonnaise side down, to a hot skillet. Top each piece of bread with 2 slices of cheese.
Cook until bread is browned and cheese is melted.
Sandwich bread slices together, cut in half and enjoy!
