Bologna is one on America’s favorite cold cuts. Then someone decided to fry a slice of bologna for a hot sandwich. The rest, as they say, is history.

Bologna is an Americanized version of mortadella, an Italian cured sausage originating in Bologna, Italy. Their are two main differences between mortadella and bologna. Mortadella has large chunks of fat and is made in sizes up to 18 inches in diameter. That’s a lot of bologna. Mortadella also has black peppercorns and some varieties have pistachio nuts.

Italian Mortadella

Traditional fried bologna sandwiches are made with butter, yellow mustard and American cheese.

Mortadella, like bologna, can be eaten cold or hot. This simple fried mortadella recipe includes lots of healthy sautéed onions and a low fat Thousand Island dressing. You can omit the onions, if you don’t like onions.

Cook’s Tip

Onions are high in antioxidants and low in calories. Add as much sautéed onions as you like. You can also replace the sautéed onions with caramelized onions for a deeper, richer flavor.
