I've been using nutritional yeast for many years. I use it mainly as a base for a popcorn/snack topping. I put about a cup or so in a blender, then add garlic & onion powders, a bit (or more) of hot chili powder, some cheese powder (if I have any), and whatever else might spark up the flavor (light on any salt, though). Run it through the blender to mix, then put it in a shaker. Good on buttered toast, pita wedges, hot popcorn...
