Shiitake Mushrooms And Brown Rice
Start the brown rice before you start the mushrooms.

Add fresh or rehydrated shiitake mushrooms (whole or sliced) to a saute pan to which you’ve also added olive oil. Add a few onions and garlic, and then add the cooked rice.
Medicinal Mushroom Soup
Make a soup out of 50 grams of fresh or dried shiitake mushrooms, vegetables, grains, and beans. This combination offers a wonderful way to boost the immune system and reduce the side effects of chemotherapy and radiation therapy.
Add 1 to 3 shiitake mushrooms per person (including children) to stir-fries, vegetables, or chicken soup to help ward off winter illnesses.
