Potato Kale Soup

My five year old liked this so much I had to make it again the next day. 

Ingredients: 
4 cups water 
Five medium potatoes, peeled and chopped
1 cup chopped kale
3 drops liquid smoke
1 tablespoon soy sauce
1 package instant miso soup
1/4 cup walnuts
1/2 cup nonfat plain yogurt
Salt and pepper 

1.) Boil the potatoes and kale in the water for 10 minutes. 

2.) Add the liquid smoke, soy sauce, miso soup, walnuts, and blend either in a blender or with a hand blender. 

3.) Stir in the yogurt. Salt and pepper to taste.

Serving suggestion: Garnish with an additional dollop of plain yogurt.
