In a bowl place the slaw, add a little olive oil and season with salt and pepper.
On the Instant Vortex control panel, press Air Fry, set the time to 8 Minutes and the temperature to 380˚F (195˚C). Press Start.
Once Add Food appears on the display, add the cabbages and close the tray.
Wait half the time and check to see how it is cooking. When Turn Food appears in the display, shake the tray to cook on all sides. Depending on the size of the cabbage, a couple more minutes may or may not be needed.
While the cabbage is cooking, in a small bowl mix all the dressing ingredients with a fork. Set aside.
Place the freshly cooked cabbage in a salad bowl and add the walnuts, the sliced Serrano ham, and the dressing. Cover well.
