A delightful twist on the classic ham and cheese sandwich, perfect for a quick and satisfying meal.
Spread one side of each bread slice with mayonnaise.
Ensure the mayonnaise is evenly spread for consistent toasting.
Layer the ham, cheese, and onion on two slices of bread, mayonnaise side up.
Distribute the ingredients evenly for balanced flavor.
Spread mustard on the other two slices of bread and place them mustard side down on the sandwiches.
Press gently to secure the sandwich layers together.
Spread butter on the outer sides of each sandwich.
Softened butter spreads more easily and evenly.
Heat a skillet over medium heat and toast each sandwich for about 4 minutes per side, until golden brown and the cheese is melted.
Use a spatula to press the sandwich slightly for even toasting.
Slice the sandwiches diagonally and serve warm.
Diagonal slicing makes the sandwich easier to handle and more visually appealing.
