For a lighter and healthier version of gnocchi, try making spinach and ricotta gnocchi. This recipe uses spinach, ricotta cheese, flour, and egg to create a flavorful and nutritious dish. Cook the spinach until wilted, chop it finely, mix it with ricotta cheese, flour, and egg, and knead the dough until smooth. Roll the dough into long ropes, cut them into small pieces, and shape them into gnocchi. Boil the gnocchi until they float to the surface, then serve with a tomato sauce or a creamy sauce.
