Start by finely chopping the onion and mincing the garlic. Having everything ready will streamline the cooking process.

In a large skillet over medium-high heat, brown the ground beef. Use a wooden spoon to break it into crumbles. This should take about 5-7 minutes. Drain any excess fat if necessary.

To the browning beef, add the chopped onion and garlic. Stir occasionally, allowing them to cook until the onion is translucent, about 2-3 minutes.

Reduce your heat to medium and stir in the ketchup, Worcestershire sauce, Dijon mustard, barbecue sauce, soy sauce, and smoked paprika. Combine everything well.

Add salt and pepper according to your preference. Let this mixture simmer for about 5 minutes, allowing the flavors to meld and deepen.

Toast the hamburger buns lightly while the meat is finishing up. Once the mixture is ready, spoon a generous amount onto each bottom half of the bun. If desired, add a slice of cheese on top while still hot so it melts.

Top with lettuce and tomato slices, and finish with the bun tops. Serve immediately and enjoy the savory delight!
