Add unsalted walnuts, nutritional yeast, garlic powder, and salt to a blender or a food processor and pulse for 30 seconds. Pulse, open or shake and repeat. Stop before you think you should, otherwise it can turn into oily clumps.
Taste and adjust flavor. Add more nutritional yeast for “cheesiness” and extra garlic powder for a more intense note.
It's important to stop, stir (or shake) and repeat, otherwise it can turn into clumpsa nd may not have the powdery texture we are looking for.If using a nutribullet , stop when I have mostly powder with a couple walnut pieces left. A couple walnut pieces are great. :)
