You soak cashews for two reasons. First, it is easier on your digestive system. Second, they blend up easier and come out smoother.
Here is what you will need.
1/2 cup soaked cashews
juice of half a lemon
1/4 cup vegetable broth
1/2 tbsp white or mello miso paste
1/2 tsp onion powder
1/2 tsp garlic powder
2 tsp dried chives (more if you like it more oniony) and you can use 1 1/2 - 2 fresh green onions
Throw everything in a blender and blend it up. That's it. Enjoy!!!
