Heat your grill to medium-high heat. Alternatively, heat the coconut oil or lard in a large cast-iron skillet over medium-high heat. 2. Gently form the ground meat into 8 small patties, about ½ inch thick. Be careful not to overwork the meat.
Season the outside of each patty with salt and pepper. 3.
Grill or pan-fry the burgers until cooked through (minimum 145ºF for beef, 160ºF for pork). During the last minute of cooking, top each patty with a slice of Swiss cheese, if using, and allow it to melt. 4. Assemble the sliders by placing each cheesy patty onto a butter lettuce leaf.
Top with a generous spoonful of warmed sauerkraut and a drizzle of Thousand Island dressing.
Serve immediately.
Don't overwork the meat when forming the patties. Handle it just enough to form the shape to ensure your sliders are tender and juicy.
