To prepare a Spanish style swiss chard with raisins and pine nuts recipe, you'll first need to gather your ingredients. Wash and trim the kale and cut it into 12 inch (1.3 cm) thick slices. Cut the stalks off the stems and chop the leaves into 1/4-inch (.6-centimeter) lengths. Chop the greens into 1-inch (0.64-cm) pieces. Toss with olive oil and season with salt and pepper to taste. Add the garlic and cook over medium-high heat until fragrant, about 5 minutes. Remove from the heat and set aside to cool.
