Although the legendary Double Burger really needs no introduction, please allow us… Tucked in between three soft buns are two all-beef patties, cheddar cheese, ketchup, onion, pickles and iceberg lettuce. Hesburger’s own paprika and cucumber mayonnaise add the crowning touch. Oh baby! Ingredients: Dr. Praeger’s Black Bean Burger, Focaccia bun, Balsamic Vinaigrette, Pesto, Tomato, Swiss Cheese
