Season the chicken breast with sea salt, black pepper, and garlic powder.
Heat a non-stick skillet over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove chicken from the pan, let it rest for 5 minutes, then slice into thin strips.
In a medium mixing bowl, combine the low-fat ricotta cheese and egg white until smooth.
Gradually fold in the whole wheat flour until a soft, slightly tacky dough forms; avoid over-mixing to keep the gnocchi light.
On a lightly floured surface, roll the dough into long ropes about 1/2 inch thick 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, which takes about 2 to 3 minutes.
In a clean skillet, melt the grass-fed butter over medium heat and add the fresh sage leaves, cooking until the butter is slightly browned and the sage is crisp.
Add the cooked gnocchi and sliced chicken to the skillet, tossing gently to coat in the aromatic sage butter before serving.
