Cook the pasta in plenty of salted water. Clean and chop the vegetables. Sauté in a pan with a little olive oil until it is pleasantly firm to the bite. Season with pepper and salt. Dice the cheese and melt it with the cream (milk) in a saucepan and bring to a boil. Season with pepper and nutmeg.
Then first layer the pasta and then the vegetables in a baking dish. Pour the cheese sauce over it and then sprinkle the parmesan over it.
Bake the casserole in a preheated oven at 180 ° C for about 10 minutes until a nice, firm cheese crust has formed.
