In a medium mixing bowl, combine the ricotta cheese, egg, grated parmesan, sea salt, and black pepper until the mixture is completely smooth.
Gently fold in the whole wheat flour one tablespoon at a time until a soft, slightly tacky dough forms, being careful not to overwork the dough.
Turn the dough onto a lightly floured surface and roll into thin ropes, then use a knife to cut the ropes into 1-inch gnocchi pillows.
Bring a large pot of water to a gentle boil and drop the gnocchi in; cook until they float to the surface, which should take approximately 2 to 3 minutes.
While the gnocchi cook, melt the ghee in a large skillet over medium heat and add the fresh sage leaves, sautéing until they are crisp and the ghee is fragrant.
Use a slotted spoon to transfer the cooked gnocchi directly from the water into the skillet, adding the diced cooked chicken breast at the same time.
Toss everything gently for 1 to 2 minutes until the gnocchi are lightly golden and the chicken is heated through, then serve immediately.
