AJ says, "I put one cup of nuts and half a cup of nutritional yeast in the blender. I add one tbsp of salt-free seasoning, but you could use a little salt or even garlic powder and/or onion powder. But even just the nuts and 'nooch' [nutritional yeast] are good. I use whatever nuts I have on hand, which could be raw almonds, raw cashews, or even raw Brazil nuts. It's also really good with 1/2 cup raw walnuts and 1/2 cup raw sunflower seeds!" Process until a smooth powder has formed. Store in an airtight container in the fridge for a week.
Chef's Note: I've also seen recipes online using sesame seeds. I imagine any of these options, or even a combination, would be great. You can also start with less nutritional yeast (3-4 tbsp), adding more to taste.
