Prepare the pasta in boiling salted water according to the instructions on the packet. Clean and chop the mushrooms. Clean and wash spring onions and cut into fine rings. Heat oil in a pan. Fry the mushrooms for 2-3 minutes, turning them, and season with salt and pepper.
Take the pan off the stove.
Pour the pasta into a sieve and drain. Mix the noodles, mushrooms and spring onions and distribute them in about 8 greased wells of a muffin tray (12 wells each). Mix eggs and milk. Season with salt and pepper.
Pour the egg-milk over the noodles and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 20-25 minutes. Remove from the oven.
Carefully lift pasta nests out of the troughs and arrange them on plates. Cut cress from the bed. Sprinkle each noodle nest with 1/2 tsp. chilli sauce and sprinkle with cress.
