Preheat your oven to 350°F (175°C).

In a bowl, combine ground beef with salt and pepper; mix gently without overworking.

Form small patties slightly smaller than the buns.

Heat a skillet over medium heat and cook patties for about 3 minutes on each side until browned. Add cheese during the last minute to melt.

Toast slider buns until golden brown.

Assemble sliders by layering lettuce, patty with melted cheese, tomato, pickles, ketchup, and mustard on each bun.
