Three Sisters Soup Recipe

This delicious recipe is my spin on a Three Sisters Soup. Three Sisters refers to a companion planting technique used for planting beans, corn and squash together. This easy, healthy and delicious version uses crookneck squash, pinto beans, sweet corn, and the beautiful flavor of sage to tie it all together! This soup can be made in an Instant Pot pressure cooker or on the stovetop and it's vegan, gluten-free, and dairy-free.
