Spinach Salad and Dressing

I got this recipe from "The Essential Mormon Cookbook" I just added a couple things. It is so good!

1 bag baby leaf spinach

1 bag lettuce
1/2 cup toasted slivered almonds

1/2 cup chow mein noodles

2 cups fresh mushrooms

2 small cans mandarin oranges (drain and rinse)

Dressing: (I can't say it is healthy but it is tasty!)

2/3 cup vinegar

1 1/2 cups sugar

2 Tablespoons chopped onion

1 teaspoon dry mustard

2 teaspoons salt

1 1/2 cups oil

Mix all ingredients, except oil, in blender. Add oil slowly while still blending. Once it is mixed you can keep it for 3 weeks in the refrigerator.

Add dressing to salad right before serving, top with the chow mein noodles and almonds.

I use about 1/3 of the dressing for this salad.
