Spread mayonnaise on one side of each of your bread slices.
2 slices bread, 1 tbsp mayonnaise
Sprinkle the grated parmesan evenly over the mayonnaise and press down with the back of a spoon so that the cheese sticks to the mayonnaise.
2 tbsp grated parmesan
Melt the butter over medium heat in your non-stick skillet.
1 tbsp butter
When the butter has melted, add one slice of bread, mayonnaise side down, into the center of your pan. Add the 3 slices of cheese and the pickles and then top the the second slice of bread, mayonnaise side up.
3 slices cheese, 2 slices pickle
Press down lightly with the back of your spatula. Cook on one side for approximately 2 - 3 minutes. Flip and cook for an additional 2 - 3 minutes.
Your sandwich is ready when the bread is toasted and browned and your cheese has melted.
Transfer to a cutting board and slice in half using a serrated knife.
Serve immediately and enjoy!
