Cook the spaghetti. Mix eggs and cream, stir in onion and garlic cubes. Season well with salt, pepper and nutmeg. Mix the drained spaghetti with the egg cream.
Twist out of the spaghetti nests and place on a baking sheet lined with baking paper. Pour the rest of the egg cream over it. Place a slice of tomato and a slice of cheese on each of the nests. Sprinkle with the herbs. Bake in a hot oven (fan oven 180 ° C) for 15-20 minutes.
