In a medium bowl, combine the ricotta cheese, egg, parmesan cheese, all-purpose flour, sea salt, and black pepper until a soft dough forms.
Bring a large pot of salted water to a gentle boil.
Using two spoons or a small scoop, form the dough into small oblong gnocchi shapes and drop them into the boiling 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 over medium heat, melt the ghee and add the sage leaves, cooking until the leaves are crisp and the ghee is slightly browned.
Add the cooked chicken breast and baby spinach to the skillet, sautéing until the spinach is wilted.
Gently fold the cooked gnocchi into the skillet, tossing carefully to coat in the sage butter without breaking the delicate pillows.
Squeeze the lemon juice over the dish just before serving to brighten the flavors.
