Soak the cashews or macadamia nuts in water for 6-8 hours, then drain and pat dry.

Slice the large red bell pepper and roast in a 400°F oven for about 20 minutes.

Blend soaked nuts, roasted red bell pepper, water, nutritional yeast, salt, onion powder, and turmeric until smooth.

Boil salted water in a large pot and cook pasta or spaghetti squash according to package instructions.

In a saucepan, heat the blended Alfredo sauce over low heat for about 5-7 minutes.

Combine cooked pasta or veggies with the Alfredo sauce, tossing to coat evenly.
