In a bowl stir together the cooked mashed sweet potato and flour (use Anthony's Goods brand to get same results) for the gnocchi until completely 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 four 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 skillet over medium heat and pour 1 tablespoon olive oil into the pan. Add gnocchi and cook on each side until golden, then remove.

In a skillet saute the minced onion and garlic in 1 tablespoon olive oil for the sauce until golden then set aside.

Add rest of ingredients for the sauce (except spinach and leave out tapioca flour if you want the sauce to be thinner) to the sautéed onion and garlic. Bring sauce to a low boil and boil for 1-2 minutes, stirring continuously (otherwise the flour will clump in the sauce) until sauce thickens. Then stir in spinach, let it wilt, and add gnocchi.
