Soak cashews for 4-6 hours, or overnight

Preheat oven to 375°

Boil macaroni for 5-6 minutes (we don't want it to overcook!)

Sauté the onion until translucent

Add the soaked (and drained) cashews, cooked onion, vegetable broth, cornstarch, and spices to a high-speed blender

Process until smooth and creamy

Add the half-cooked macaroni to a baking dish lightly greased with olive oil

Pour the sauce mixture over macaroni, and stir to coat noodles

Finish with the optional bread crumbs and cheeze

Bake for 15 minutes, you'll see the mixture bubbling nicely

Let cool before devouring!
