6 slices firm, thinly sliced close-textured bread, such as Pepperidge Farm
3 tablespoons sweet butter, softened
3 thin slices honey-cured ham
1/4 pound sliced Gruyere cheese, white cheddar, or Swiss
To assemble the sandwiches, butter both sides of each bread slice. Lay ham and cheese on one slice and cover with the another slice. Trim the crusts off the sides.
Heat a saute pan over medium-low heat, then fry the sandwiches until the cheese starts to melt and the sandwiches are golden brown, about 3 minutes on each side. You may need to add more butter to the pan.
Remove the sandwiches to paper towels to drain, let them cool for 1 minute, then cut into quarters diagonally and serve 3 quarters each per serving.
