Let’s get cooking! Here’s how you can make these burgers in a jiffy:

1. In a large bowl, combine the ground beef, salt, pepper, and Worcestershire sauce. Mix gently with your hands until just combined, being careful not to overwork the meat.
2. Divide the mixture into four equal portions and roll each into a ball.
3. Heat the olive oil in a large skillet over medium-high heat. Once hot, place the beef balls into the skillet and smash them down with a spatula to form thin patties.
4. Cook for 3-4 minutes on each side, or until the edges are crispy and the burgers are cooked through. Top each patty with a slice of cheddar cheese and let it melt.
5. While the patties are cooking, prepare your sauce by mixing together the mayonnaise, sugar-free ketchup, dill pickle relish, vinegar, onion, and mustard in a small bowl.
6. Assemble your burgers by placing each patty on a large lettuce leaf, adding a generous dollop of sauce, and layering with your choice of optional toppings.
7. Wrap the lettuce around each burger and serve immediately for the best flavor and texture.

Quick tip: Using a spatula to smash the burgers helps create those crispy edges that make these smash burgers so irresistible. Plus, it’s a fantastic way to get the kids involved—my oldest loves being in charge of the “smashing” process!
