For the noodle casserole, cook the noodles until al dente. Coarsely dice vegetables, finely chop onion and ginger and sauté in olive oil with a little butter.
Add vegetables, roast, pour mineral water, steam until not too soft. Mix the pasta with the vegetables and the diced mozzarella.
Pour into a buttered baking dish. For the topping, whisk all the ingredients together and empty into the baking dish. Cover the dish with foil, bake at 180 °C preheated oven for about 45 minutes.
Remove the foil, sprinkle with Parmesan, bake again in the oven with grill function.
