Heat the vinegar and add the sugar and seasoning packets. Stir until dissolved. Add the oil, and refrigerate for at least four hours (preferably overnight). Coat the almonds in olive oil and toast lightly (either in a toaster oven or in a frying pan). Break up the Ramen noodles into small/medium pieces into a large bowl. Layer the cabbage on top of the noodles. Add sunflower seeds, toasted almonds, chopped green onion, and Craisins. For a very crunchy salad, pour the dressing over the salad and toss shortly before serving. For softer noodles, pour the dressing over the salad, refrigerate overnight, and toss shortly before serving.
