Heat about 2 tbsp of olive oil medium heat in a large saute pan. After chopping the kale, submerge it in water & swish it around to get it nice and clean. Remove from water and shake off excess water. Add the pine nuts and garlic to the oil in the pan, and cook for about 2 minutes or until the nuts start to sizzle. Add the raisins and kale, stir and cover. Cook until the greens wilt, stirring occasionally (about 5 minutes). Remove the cover and season with salt and pepper. Turn the heat up to high and cook for about another 2 minutes, or until the liquid evaporates.
