Preheat your oven to 350°F (175°C).

In a bowl, mix ground beef with salt and pepper until just combined.

Form the meat mixture into 8 small patties, slightly larger than the buns.

Heat oil in a skillet over medium-high heat and cook patties for 3-4 minutes on each side; add cheese during the last minute to melt.

Assemble sliders by placing patties on bottom halves of the buns; top with ketchup, mustard, and pickles before adding the bun tops.

Bake assembled sliders in the oven for about 10 minutes until buns are toasted.
