Spinach and ricotta gnocchi is a delicious and healthy alternative to traditional potato gnocchi. To make this dish, you will need spinach, ricotta cheese, flour, and eggs. Cook the spinach until it is wilted, then chop it finely and mix it with the ricotta cheese, flour, and eggs. Roll the dough into long ropes and cut them into small pieces. Boil the gnocchi until they float to the surface, then serve with a tomato sauce.
