Aunt Rauna 's Poppy Seed Dressing

1-1/2 C olive oil

1-1/2 C red wine vinegar

1 C sugar

2 tsp salt

1 tsp dry mustard

1 tsp poppy seeds

grated purple onion (or substitute 2 tsp onion powder)

Mix well and use on our favorite spinach salad. This makes a lot.  I half the recipe and it's still plenty.
