Preheat grill. Season beef with salt and pepper, and form into 8 small, thin patties.
Evenly divide 3 ounces of cheese in the center of 4 patties. Top with remaining patties, and firmly press edges to seal. Place sliders on grill.
Just before sliders reach desired internal temperature, top with remaining sliced cheese and cook for 1-2 additional minutes, or until cheese begins to melt.
Layer garnishes and bacon on bottom buns; transfer sliders to buns and serve.
