I use my small food processor to make this. I think it holds 3 cups.
Put the almonds, yeast, and garlic powder in the food processor. Pulse until it looks like a grain.
Add a drizzle of olive oil and processor more until the granules became very small (note: pic is zoomed in).
Taste, add salt, blend - repeat until it's just the way you like it. I like to make mine very salty because I use the mixture instead of salt in recipes.(Honestly, you want it to look like that Parmesan grated topping you used as a kid).
