Kneaders Turkey cranberry Sunflower Salad

This is my knockoff of a salad I adore. I omit the
Turkey, Maryjane Melis added this.

Salad mix - 1/2 Spinach 1/2 Spring Mix dark brown Mushrooms cut into large pieces Roasted and salted sunflower seeds dried cranberries Turkey (optional) Salad Dressing 1 1/2 cups sugar 2 teaspoons dry mustard 2 teaspoons salt 1 cup red wine vinegar 2 to 3 Tablespoons grated red onion 1 3/4 cup salad oil - to be drizzled in blender 2 Tablespoons poppy seeds to be stirred in last. Put first five ingredients in blender and blend until well blended. Drizzle in oil slowly until blended. Then stir in poppy seeds. This makes almost a quart of dressing. It keeps in fridge for awhile. Stir dressing in salad before adding sunflower seeds and they won't all go to the bottom of the bowl.  Add turkey but it's great without it.
