I halve the recipe for the dressing in the "Apple and Spinach Salad" in 3FC recipes. If you have tastebuds that like a little citrus and a little spice, try this:
Mix one tablespoon orange juice, one tablespoon lime juice, one teaspoon dijon mustard, and one teaspoon honey. It's only 37 cals for quite a bit of dressing. I have it with 20 cals (a large plate) of spinach, and it's my 57 cal wonder snack!!!
