Stir fry the onion
3 minutes. Increase the heat, and add the mushrooms in batches, fry
5 minutes on high heat. Add the mince beef and stir fry 4 minutes more.
Add the wine and pepper and salt to taste and heat well. In a separate
pan, melt the butter. Add the flour and simmer while stirring for 3
minutes. Add the milk and bring to the boil, stir well. Simmer for three
minutes. Add salt, pepper and nutmeg to taste. Put some lasagna sheets
on the bottom of a greased lasagna dish. Add 1/3 of the meat-mushroom
mixture, sprinkle with 1/3 of the cheese, and distribute 1/3 of the
truffle slices over it, spread 1/4 of the white sauce on top cover with
lasagna sheets. Repeat this process twice more. Finish off with the
remaining white sauce. Bake the lasagna 45 minutes in the oven at 10
degrees Celsius.
