Cook the pasta in boiling salted water according to the instructions on the packet. Clean and wash the broccoli and divide into very small florets. Add to the pasta 3 minutes before the end of cooking time. Drain the pasta and broccoli and let them drain.
Clean, wash and cut the peppers into small pieces. Drain the corn. Cut cabanossi into slices. Mix crème fraiche, milk and eggs. Season with salt, pepper and a little nutmeg.
Put the noodles, vegetables and cabanossi slices in a greased casserole dish. Pour egg milk over it. Leave to stand in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 25 minutes.
Sprinkle the cheese over the casserole 10 minutes before the end of the cooking time. Arrange the casserole on plates and garnish with frisée salad if desired.
