Cook pasta of choice according to package directions.
While the pasta is cooking, pour a can of full-fat coconut milk into a saucepan and add water, salt, nutritional yeast, garlic, and tapioca starch to the milk and give it all a stir.
After the ingredients are mixed, turn on the heat to medium-low and heat the sauce while stirring frequently until it starts to boil and thicken.
Allow it to boil for about 30 seconds and then turn off the heat.
Once the pasta has been cooked, drained and rinsed, pour the Alfredo sauce over it. Mix well and serve hot.

Notes
Use full-fat coconut milk for this recipe.
You may sub the coconut milk and water for 1 3/4 cups of plain soy milk and 1/4 cup neutral-flavored oil.
For a Smoked Gouda Alfredo, simply add 1-2 tbsp liquid smoke to the sauce. (I use Colgin brand. Some brands of liquid smoke are stronger than others, so you may want to add a small amount and then taste it.)
You may sub corn starch, potato starch, or arrowroot powder for the tapioca starch, but it will not deliver the same texture.
