Cafe Zupas Poppyseed Dressing

For the Poppyseed Dressing:
1/2 cup apple cider vinegar
1 teaspoon dry mustard powder
1/4 cup red onion, chopped
1/2 teaspoon salt
1 tablespoon poppy seeds
3/4 cup sugar
1 cup vegetable oil (I used half canola, half olive)
For the salad:
16 ounces baby spinach
about 3 cups sliced strawberries
6 ounces bleu cheese, crumbled
1/2 cup sliced almonds, toasted

Add all the dressing ingredients to a blender and blend until smooth. Set aside.
Toss all the salad ingredients except the almonds in a very large bowl. Add as much of the dressing as you want. Add the almonds. Toss and serve immediately.
