These Smoked Cowboy Beef Sandwiches start with a chuck roast rubbed in bold barbecue seasoning and smoked low and slow. Then the magic happens — the beef is braised in a rich mixture of Coca-Cola, beef broth, jalapeños, garlic, onions, and smoky bacon until it’s fall-apart tender. Pile it high on a bun with Colby Jack cheese, crispy bacon, fried onions, and pickles for a sandwich that’s smoky, cheesy, and downright irresistible.
