Slice the chicken breast into bite-sized pieces and season with half of the sea salt and black pepper.
Sauté the chicken in a non-stick skillet over medium-high heat until browned and cooked through, then remove and set aside.
In a medium bowl, whisk together the part-skim ricotta cheese, egg white, grated parmesan cheese, and the remaining salt and pepper until smooth.
Gently stir in the whole wheat flour until a soft, slightly tacky dough forms, being careful not to overwork it.
Bring a large pot of water to a gentle boil and drop teaspoon-sized portions of the ricotta dough into the water.
Boil the gnocchi until they float to the surface, which should take about 2 to 3 minutes, then remove with a slotted spoon.
Melt the ghee in the same skillet used for the chicken and add the fresh sage leaves, cooking until they are crisp and fragrant.
Add the gnocchi, cooked chicken, and fresh spinach to the skillet, tossing gently until the spinach is wilted and the gnocchi are lightly golden.
