Poppy Seed Dressing

This goes great with any salad with bitter greens. I think I stole it from http://www.allrecipes.com

1/3 cup white sugar
1/2 cup white vinegar
1 teaspoon salt
1 teaspoon ground dry mustard
1 teaspoon grated onion
1 cup vegetable oil
1 tablespoon poppy seeds

Blend together for a while till smooth.
