Dad always made these on Sunday afternoons. Just 3 ingredients. A crunchy, savory treat that totally replaces potato chips.

Try using different types of salami, like spicy Calabrese or a smoked variety, to change up the flavor while keeping the recipe just as simple. If you like a little heat, add a pinch of red pepper flakes along with the black pepper before baking. For an herby twist, sprinkle a tiny bit of dried Italian seasoning or dried oregano over the cheese. You can also swap the Parmesan for finely grated Asiago or Romano for a sharper bite, just keep the same light sprinkle so they stay crisp. If you’re meal-prepping snacks for the week, bake a double batch and store them in a loosely covered container so they don’t lose their crunch—then just re-crisp for a minute or two in a hot oven if needed.
