Let’s get cooking! Follow these simple steps to create your own Mini Big Mac Cheeseburgers:

1. Start by preparing the special sauce. In a small bowl, mix together the mayonnaise, ketchup, sweet pickle relish, white vinegar, and yellow mustard. Set aside in the refrigerator to allow the flavors to meld.
2. In a large bowl, combine the ground beef with salt and pepper, mixing gently to incorporate. Form the mixture into six small patties, about 2 to 3 inches in diameter.
3. Preheat a skillet or grill over medium-high heat. Once hot, add the patties and cook for 3-4 minutes on each side, or until they reach your desired level of doneness. Add a slice of cheese on top of each patty during the last minute of cooking to allow it to melt.
4. While the patties are cooking, lightly toast the mini burger buns in a separate pan or in the oven.
5. Assemble the burgers: Spread a generous amount of the special sauce on the bottom half of each bun, layer with shredded lettuce, a cooked patty, chopped onions, sliced pickles, and the top bun spread with a bit more sauce.

Remember, cooking is about having fun and making the recipe your own. Don’t be afraid to adjust seasonings or toppings to suit your taste!
