Soak the cashews in hot water for at least 30 minutes. Prepare your chopped veggies.
Strain the cashews and add to a blender with the rice milk. Blend until smooth.
Add the veggies, spices, rice milk mixture, and broth to your Crockpot™ 6qt Easy-to-Clean Slow Cooker. Mix to combine. Cook on high for 4 hours. When 30 minutes remain, mix together the cornstarch and water in a small bowl and mix into the soup.
Prepare your biscuits according to package instructions or recipe.
Serve the soup, topping each bowl with extra dried parsley and a biscuit.
