How about turkey bacon?
The benefit of turkey bacon is that it's leaner and contains less fat than pork bacon. Which is cool if you're worried about that. It's not cool if you're using the bacon to infuse fat, like this recipe does. The purpose of the bacon (besides the flavor) is to add some fat into the bacon-infused ground beef burger so it's nice and juicy. Without that fat, the burger would be really dry.
