whenever we go to visit relatives in New Mexico, we always come home with this certain bologna that we can’t find her in California... it has this red casing... my dad grew up eating it and just loves it... and the rest of us have come to like it too—it just reminds us of visiting New Mexico when we were kids... we probably made it out there every 3 years on a road trip... we call it New Mexico bologna or red bologna... my cousins all know that we like it, so they always make sure to serve it fried at at least one breakfast while we are there...
You are probably talking about Coronado Bologna. I grew up eating it too, but my mom bought the ring bologna that was much smaller in diameter and you had to slice it yourself. She'd cut it into thick slices and fry it until it was crisp. It was great in sandwiches or when we were particularly broke it was our meat for supper, usually put into fried potatoes to eat in a homemade flour tortilla. Heaven!
