Cook the pasta in boiling salted water according to the instructions on the packet. In the meantime cut the sausage into slices. Wash the thyme, shake dry and, except for a little to garnish, pluck leaves from the stalks. Wash and clean the zucchini and cut into strips. Clean, wash and halve the tomatoes. Peel shallots and cut into slices. Pour the pasta onto a sieve, rinse briefly in cold water and drain.
Beat the eggs, milk, cheese and thyme. Season with salt, pepper and nutmeg. Mix the pasta, sausage and vegetables and place in a greased, ovenproof dish (1.4 litres capacity). Pour egg-milk evenly over the pasta. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 45 minutes. Garnish with thyme
