What's a good substitute for pancetta?

Pancetta is the same cut as American bacon, so that's the first substitute that comes to mind. Canadian bacon, salt pork, prosciutto, smoked ham, and smoked sausage are all good choices as well.

The Mr. Stripey Tomato, Arugula, and Pancetta Sandwiches from Cooking Light is a great example of a recipe where substituting cured bacon for the pancetta works just fine. For more information on substitutions, see our Ingredient Substitutions guide.
