Tips and Tricks:

  1. A serving = One cup of soup. The nutritional information does not include soy sauce or sriracha.
  2. For Paleo and Whole 30 compliant clear onion soup, use Coconut Aminos instead of Soy Sauce.
  3. I usually don’t throw away the strained vegetables, but toss them in with another meal instead.
