the pepper jack bologna looks good, I am usually not a fan of cheese in the meat, but that doesn't stop me from eating it.
We had a small meat place that used to make jalapeno kielbasi no cheese like all the other places around. He also made patties out of it, they were probably 5" so nice to make one of them and a regular burger patty for your double cheeseburger. It was great stuff, I would stop and grab 3 or 4 pound of it and when I for out to the car just rip a chunk of for a snack.
