First you'll need a crusty loaf of bread sliced in thick slices (the recipe is for 4 slices)
Cook 5 small potatoes until tender and smash them.
Then make a bechamel sauce by melting 2 tbsp of butter in a heavy saucepan.
Bake on a baking sheet until cheese is golden and bubbling. 12 to 14 minutes, check from time to time.
Plate your croque monsieur with a fresh green salad and voila...delicieux!!
