In a sizeable shallow dish, whisk the eggs together with pinches of salt and pepper. Once mixed, set the dish aside for later use.
Commence assembling the sandwiches. Spread mustard and mayonnaise on each slice of bread. Layer the slices with baked ham and shredded Gruyere cheese. Season the layers with additional salt and pepper as per your taste preference. Gently press the sandwiches to ensure the fillings are compact.
Preheat a skillet over medium heat. Add the unsalted butter to the skillet, allowing it to melt completely.
Carefully dip each sandwich into the previously prepared egg mixture, ensuring both sides are well coated.
Place the egg-dipped sandwiches into the skillet. Allow them to cook for approximately 2 to 3 minutes on each side, or until they achieve a golden brown coloration.
Once cooked, the Monte Cristo Sandwiches are ready to serve. For an additional layer of flavor, you may choose to top them with powdered sugar, honey, or fruit preserves, although these are optional.
