What is new boss burger?

As an AI language model, I do not have access to the latest updates in the food industry. However, an online search shows that Boss Burger is a relatively new addition to the fast-food burger scene. It is a giant burger made with two flame-grilled beef patties, American cheese, bacon, onion rings, lettuce, tomato, and special Boss sauce, all served on a sesame seed bun. It is available at certain fast-food chains and restaurants, and is popular among burger enthusiasts.
