Slow Cooker North Woods Wild Rice Soup

Why I Love This Recipe
This is a wonderful soup that will please the most gourmet tastes along with the simpler tastes of children. I substituted fresh sliced asparagus for the peas and added shitake mushrooms. I also threw in some fresh fennel leaves because I had them on hand. It is now one of my most requested company dinners.
variation... substitute corn for the green peas, and add barley.
