Drop small flat mounds of shredded mozzarella (about 2 cups) on the sheet, spacing 1 inch apart. Make 12 mounds.
Sprinkle each mound with Italian seasoning (½ teaspoon in total).
Top each mound with a slice of pepperoni (12 slices).
Bake for about 12 minutes, until edges are golden brown.
Allow to cool a few minutes before removing from tray. Chips continue to crisp as they cool.
Serve warm with your favorite keto-friendly dip.
Notes
Try different cheeses or toppings to vary the flavor. Store in airtight containers in the fridge for best crunch retention. Reheat in oven briefly to bring back crispiness.
