Season the chicken breast with half of the sea salt and black pepper, then grill or pan-sear until fully cooked to an internal temperature of 165°F.
In a medium mixing bowl, whisk together the ricotta cheese, egg, parmesan cheese, and the remaining salt and pepper until smooth.
Gently fold in the flour one tablespoon at a time until a soft, slightly tacky dough forms, being careful not to overwork it.
Bring a small pot of water to a gentle boil and drop small spoonfuls of the ricotta dough into the water, cooking until they float to the surface, about 2-3 minutes.
In a separate skillet, melt the ghee over medium heat and add the minced garlic and sage leaves, sautéing until the sage is crisp and the ghee is fragrant.
Add the cooked gnocchi and baby spinach to the skillet, tossing gently for 1 minute until the spinach is wilted and the gnocchi are lightly golden.
Slice the cooked chicken breast and serve it alongside the gnocchi, drizzling any remaining sage butter from the pan over the top.
