A croque monsieur served with a poached or lightly fried egg on top is known as a croque madame (or, in parts of Normandy, as a croque à cheval). The name croque mademoiselle is associated with a lighter, vegetarian version that's made of the same bread, but with ordinary melting cheese, accompanied with chives, cucumber, and green salad. A monte cristo is another type of French sandwich, also made with ham and Gruyère. It is dipped in egg custard and pan fried. It is served with jam or syrup.
