Brush Mayo on the the outside of both slices of bread, Layer all four cheese on both slices of bread for (4 slices on each piece of bread
Light grill to low heat (hold your hand 1 inch over the grate and count to at least 5 comfortably) About 375-400 Degrees F.
Lay the bread on the grill over direct heat and cook for about 1 minutes then rotate the bread a quarter turn to get grill marks (keep a close eye and make sure the bread doesn't char)

Once the cheese is completely melted remove the grilled cheese from the pan and assemble the sandwich, slice and enjoy.
