Cook the asparagus stalks in salted water with a pinch of butter until just barely done.
Mix the milk with the eggs, the flour and a little salt and let it soak. If desired, mix in some finely chopped parsley and bake 4 thin crepes in a non-stick pan (26 cm).
Place a slice of boiled ham on each of the crepes and spread the asparagus stalks on top. Roll up and place in a buttered baking dish. Sprinkle with grated cheese and bake in the oven at 200 degrees for about 20-30 minutes.
