Keto pork rinds basically act like a potato chip substitute, so you'll find the same flavors you would find in potato chips.  You can buy BBQ, Pizza, Nacho Cheese, Sour Cream and Onion, Salt & Vinegar, and Sea Salt & Black Pepper flavors of Keto pork rinds in grocery stores and on Amazon.  You can even buy chicken skin that is prepared like pork cracklings.
