Cook 16oz bag of pasta according to package instructions

Warm a pan over medium heat. Add olive oil and and sauté onion until soft and translucent. Then stir in garlic for 30 seconds or so. Be careful not to burn.
 Remove from heat.

In a blender add the roasted beet, soaked cashews, almond milk, lemon juice, salt, pepper and the onion and garlic mixture. Blend on high until smooth and creamy. I like to use the soup setting on my @vitamix to warm the sauce as well.
