What other meat can I use instead of pork in a Spaghetti Carbonara? I don't want to eat pancetta (or pork) but I want to be able to recreate a similar taste and texture. 

What can I substitute for the pancetta?
Bacon is often substituted for pancetta. While bacon is also traditionally made from pork, there are companies that produce bacon from turkey, beef, lamb, venison, elk, buffalo and even seitan. If you could find one of these bacons in your area, then you could substitute one of them for the pancetta.
