You can ask the deli department to cut a quarter inch slice of pancetta for you. I usually get 4- quarter inch slices and use them like bacon to add to salads, roasted vegetables etc. I always have some on hand.
You can change this dish up if you wanted it to be vegetarian, by eliminating the pancetta. Make it vegan by also skipping the parmesan cheese. Since those two ingredients add a salty element, consider adding in some chopped olives or capers -- and golden raisins for a sweet hit.
