Simply mix all of the sauce ingredients into a bowl. Cover the bowl and place it in the refrigerator at least one hour before serving.
For the Burger
First, preheat an electric griddle to 400 degrees. Toast your buns by laying them face down on the griddle for about a minute, and set aside.
Form the ground beef into thin patties, slightly larger than the bun. Cook patties on the hot griddle for 2 to 3 min per side. Pinch a bit of salt and pepper and sprinkle it over each patty.
Once the patties have cooked, it's time to assemble the burgers. Take the bottom bun and spread the sauce over it. Then stack the ingredients in the following order: 1 beef patty, 2 tomato slices, 2 lettuce leaves, 2 pickles, a handful of diced onions, and top bun. Serve hot and enjoy.
Notes
If you'd like to turn this into a Jumbo Jack Cheeseburger, simply sandwich your meat patty between two slices of American cheese.
Double the amount of meat if you want to make a Double Jack.
