I know I'm far from the first one to post about these, but they are such a satisfying, crunchy Keto snack. Bake a layer of pepperoni slices at 425 for about 10 minutes, turning halfway through. Warning: I threw out the first batch I made in the toaster oven because they burned black well before the time was up, but who wants to turn on the oven on a 90-plus degree day? Next batch I just checked every few minutes. Counts for 12 Boar's Head pepperoni slices (could have eaten three times that much but I'm on a fat fast): 105 cals, 1 carb, 10 fat, 5 protein. Great with onion dip.
