In a large bowl, add ingredients for the beef patties. Using your hands, mix together ingredients until well-combined. Form the mixture into small sliders, approximately 2 to 2 1/2 inches in diameter. You should have 12 in total.
Heat a cast iron skillet or grill to medium-high heat.
Cook patties to desired temperature, approximately 2-3 minutes per side for medium rare.
In the last minute of cooking, top each patty with a slice of sharp cheddar cheese. Cover skillet or close grill lid to allow the cheese to melt.
Spread the bottom of each bun with ketchup. Add cooked patties to the bottom halves of the toasted buns.
Top with a slice of pickle and a generous portion of LAY'S® Classic Potato Chips. Finish with the top halves of the buns.
Brush tops with melted butter and sprinkle with sesame seeds.
