Make the sliders: In a medium bowl, mix the ground beef, breadcrumbs, egg, mustard, ketchup, and garlic powder together with a wooden spoon. Season to taste with salt and pepper and stir gently to combine. Form the mixture into small patties.
In a large skillet over medium heat, heat the vegetable oil. Add the beef patties and cook for about 3 minutes, until the bottoms develop a nice seared crust. Flip and cook for another 1-2 minutes, then add the cheese slices to the tops of the patties. Cover the pan with a large lid and cook until cheese melts.
Assemble the sliders: Place 10 pickle chips (or however many patties you have cooked) on a serving platter. Top with lettuce, tomato, and a cooked patty. Top with another pickle chip and serve immediately.
