Preparation
Chop the one onion for the broth. Thinly slice the two onions and garlic, which will later be added to the broth and let them all sit for 5 minutes to bring out their health-promoting properties.
To prepare broth, heat 1 TBS broth in medium soup pot. Healthy Sauté chopped onion over medium heat for 5 minutes, stirring frequently, until translucent. Add the rest of the broth and remaining broth ingredients and stir. Bring to a boil, reduce heat to medium low, and simmer broth ingredients briskly together for 20 minutes, uncovered. This will bring out a lot of flavor from the ingredients.
In a separate medium sized stainless steel skillet, heat 1 TBS of soup broth over medium heat. Healthy Sauté sliced onions over medium low heat in broth, stirring often for about 15 minutes, until translucent. Add garlic and sauté for another minute.
After cooking broth for 20 minutes strain while it is still hot and return liquid to pan.
Slice mushrooms (and discard rest of strained ingredients) and return to broth.
Add sautéed onions and garlic and season with salt and white pepper to taste.
