This 4 ingredient, 5 minute recipe is the perfect topping for any pasta, soup, salad, or anywhere you would use parmesan. Keep a jar on hand at all times!
Add all the ingredients to a food processor and pulse several times until it's broken down into a fine crumbly texture, scraping down the sides as needed. I like a bit of texture in mine, but if you prefer a powdery texture, pulse a few times more.
