How to make
Cut the zucchini into strips with a potato peeler and stew it with a little garlic and salt.
Once it is ready, we can make the sauce. For the sauce, stew the mushrooms and onions with a little butter.
Then mash the tomatoes and add them as well. Wait until the mixture boils and thickens.
Once our sauce is ready, pour it over the zucchini and sprinkle it with Parmesan.
