Spaghetti Salad

1 lb spaghetti (cooked and rinsed with cold water) 1 jar pimentos 8 oz parmesan cheese 1 jar salad supreme 1 small green pepper (chopped) 1 can sliced olives 1 small red onion (chopped) 1 large bottle Wishbone Italian dressing (reserve at least half of the bottle until you serve salad) Mix all ingredients and cover. Refrigerate so all flavors can blend (I usually refrigerate overnight). Before serving, stir salad really well and add remaining dressing to moisten at last minute.
