The Croque Monsieur is a rich, cheesy baked sandwich originating in France. Traditionally using Bayonne ham, Gruyere cheese and the classic French mother sauce, Bechamel. The Croque Madame is the same thing but with a fried egg on top.
This is a variation of the Tortilla Española. A thick Spanish omelette traditionally made with potatoes poached in olive oil. It’s often served at room temperature and cut into small pieces for appetizers. Substituting potato chips for the olive oil poached potatoes offers a quick and tasty shortcut. There are countless ingredients that can go into this omelette or just slice it into large pieces and eat it with bacon.
