For an extra layer of flavor, spread a thin layer of Dijon mustard on the bread before dipping it in the cheese sauce. Gruyère cheese is recommended for its nutty and complex flavor, but you can substitute with other cheeses like Emmental or Comté. If you don't have time to make a cheese sauce, you can use a high-quality store-bought béchamel sauce. For a vegetarian version, replace the ham with sautéed mushrooms or roasted vegetables. To make ahead, assemble the sandwich and refrigerate until ready to cook. Add the fried egg just before serving. Serve with a side of mixed greens or a simple salad for a complete meal.
