Melissa's Poppyseed Dressing

Ever tasted Melissa's fabulous spinach salad and wondered about the incredible dressing that she makes to go with it? (I did)  She let me take a picture of her well-loved recipe to post here for you ladies...

I believe she said that she just blends all the ingredients and then adds the poppy seeds last.

If you can't read the image, the recipe is:
1 small white onion
1 1/2 c sugar
2/3 c cider vinegar
2t dry mustard
1 1/2 t salt
2 cup oil
2-3 T poppy seeds

Melissa puts this over spinach salad - and usually includes strawberries in that yumminess.
Thanks for sharing, Melissa!
