Place mayonnaise in a medium bowl. Drain pineapple; reserve juice. Add pineapple to bowl and mix. Add enough of the reserved juice so the mayonnaise has the consistency of ketchup. (Discard the rest of the juice). Add cabbage and toss well. If possible, chill before serving. Immediately before serving, add peanuts and raisins and toss. Sprinkle paprika on salad and serve. Serves 4.
