Add all ingredients to a high-speed blender (i.e. VitaMix)
Blend on high speed for 2 minutes.
Transfer to a large sauce pan and cook on medium heat, stirring frequently to prevent sticking, until thick and bubbling.
Remove from heat and serve over pasta** with optional pasta topping.
Notes
*If using a VitaMix or other high-speed blender, there's no need to pre-soak cashews.**Use your favorite chickpea or lentil pasta for a high-protein, whole food meal.
