Monsieur ou Madame ?

On the left above is the French sandwich called a croque-monsieur. It's made with sandwich bread (pain de mie), a sauce béchamel (a white sauce made with butter, flour, and milk), grated cheese, and ham, and then baked in the oven. On the right is the sandwich called a croque-madame. The only difference it that it has a sunny-side-up egg on top.

Fry an egg separately and then place it on top of a baked croque-monsieur. We made these sandwiches yesterday and ate them with air-fryer French fries, followed by a salad of green beans, diced tomato, and vinaigrette dressing.
