In a medium bowl, combine the ricotta cheese, egg, grated parmesan, sea salt, and black pepper, mixing until smooth.
Gently fold in the cassava flour one tablespoon at a time until a soft, slightly tacky dough forms.
Bring a large pot of salted water to a gentle simmer. Using two spoons or a small scoop, drop walnut-sized portions of dough into the water.
Boil the gnocchi for 2-3 minutes or until they float to the surface, then remove with a slotted spoon and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced chicken breast and cook until golden and cooked through.
Add the minced garlic and fresh spinach to the skillet, sautéing until the spinach is just wilted.
Add the boiled gnocchi to the skillet along with the lemon zest and lemon juice.
Toss everything together gently for 1 minute to allow the flavors to meld and the gnocchi to develop a light golden crust before serving.
