Form the Patties: Divide the ground beef into 4 equal portions. Gently shape them into thick patties, making them slightly larger than your buns as they will shrink slightly during cooking. Press a slight dimple into the center of each patty with your thumb to keep them flat while cooking.
Season & Grill: Season both sides of the patties heavily with salt, pepper, garlic powder, and onion powder. Fire up the grill to high heat. Place the patties down and sear for about 4 to 5 minutes per side.
Melt the Cheese: During the final minute of cooking, place a slice of sharp cheddar cheese onto each patty and close the grill lid until fully melted. Simultaneously, toast your buns lightly on the cooler side of the grill.
Mix the Sauce: In a small bowl, whisk together the mayonnaise, ketchup, sweet relish, and yellow mustard until perfectly smooth.
Assemble the Layered Crunch: Spread a generous layer of special sauce on both the top and bottom buns. Place the cheesy burger patty on the bottom bun, followed by a slice of tomato and a crisp leaf of lettuce. Just before closing the burger, pile a generous handful of salted potato chips directly on top of the lettuce.
Serve: Press down gently, hear that satisfying crunch of the chips, and serve immediately!
