Place all vegetables in a medium saucepan. Add enough water to cover. Bring to a boil, cook until soft.
Place cashews in a small bowl. Pour 1/2 cup boiled vegetable water over the cashews and allow to soak while vegetables are cooking, about 10-15 minutes.
Put softened cashews and their water in a blender, blend until smooth.
Add cooked vegetables, seasonings, and 1 cup of the almond milk to the blender. Blend until smooth. Taste the sauce. Add more almond milk for a thinner consistency, adjust seasonings to taste.
Serve 2 1/2 cups of sauce over cooked pasta. Try leftover sauce on nachos, tater tots, or in soup. Enjoy!
