Bring 6 quarts water to a rolling boil and add 2 tablespoons salt.

Cut the cabbage into 2-inch ribbons. Add the cabbage to the boiling water and cook until tender, about 6 minutes. Drain well and set aside to cool.

In a 12 to 14-inch saute pan, heat the olive oil over a medium-high flame until hot but not smoking. Add the onions and garlic and cook until soft about 5 minutes. Add parsley, fennel seeds,cooked cabbage and chili flakes, then toss to mix and remove from heat.

Lay the pork pieces out flat on a board and season well with salt. Divide the cabbage mixture over the 4 pieces and fold the pieces across to create a pocket, close and secure with toothpicks.

Heat 4 tablespoons extra-virgin olive oil in another 12 to 14-inch saute pan over medium heat. Place the pork pockets in the pan and cook until golden brown on both sides. Add the wine, lower the heat to medium-low and simmer 10 minutes. Remove the pork to a plate, swirl the remaining olive oil into the pan, add chopped parsley to the liquid, pour over the pockets and serve.
