Swedish-style hot dogs consist of a thin flatbread stuffed with mashed potatoes and one or two hot dogs before being topped with shrimp salad, ketchup, Swedish mustard, mayonnaise, salad greens, and crispy onions. Diners can opt out of any topping, replace the hot dogs with hamburger meat or reindeer stew, or choose different toppings like cheese, slaw, and peppers.
