Place the ricotta in a fine-mesh strainer for 15 minutes to remove excess moisture.
In a medium bowl, combine the drained ricotta, egg white, sea salt, and black pepper until smooth.
Gently fold in the flour until a soft dough forms, being careful not to overwork it.
Turn the dough onto a floured surface, roll into long ropes, and cut into 1-inch pieces.
Bring a large pot of salted water to a boil and cook the gnocchi until they float to the surface, then drain.
In a large skillet over medium heat, melt the ghee and add the fresh sage leaves until they become crisp and fragrant.
Add the cooked gnocchi, shredded chicken breast, and fresh spinach to the skillet.
Toss everything together until the spinach is wilted and the gnocchi are lightly golden.
Serve immediately topped with a sprinkle of grated parmesan cheese.
