I threw together a bunch of immunity boosters in my InstaPot, crossed my fingers, and what I got was a delicious nutritious soup that I would recommend to anyone who wants to boost their immune system while enjoying the most savory delicious soup! I used the powerful medicinal shiitake mushroom for their amazing immunity powers and kombu seaweed for minerals and digestibility of beans.  I added salt afterwards because I grew up hearing that salting beans kept their skin tough, don't know if it's true or not, but I just add salt later on!  I served this with a nice crusty sourdough and arugula salad. Yum!
