In a food processor or bowl combine ingredients for gnocchi until smooth. If you don't have cooked sweet potato on hand, make it by peeling a large sweet potato, cutting into 2" chunks, and boiling in water until soft (drain water from sweet potatoes after boiling).

Separate dough into eight equal parts and roll out into 3/4" diameter tubes on a surface dusted lightly with cassava flour. Cut the tubes of dough into 1" pieces.

Bring a large pot of water to a boil and drop gnocchi into it. Once they have risen to the surface, remove, and drizzle lightly with olive oil.

Heat a non-stick skillet over medium heat and drizzle with olive oil. Add gnocchi and cook on each side until golden, then remove.

In a saucepan simmer ingredients for sauce for about five minutes. Add kale and wilt in sauce. Serve with gnocchi.
