Mix the hamburger, onion soup mix, milk, and peanut butter together in a bowl. Spread this mixture on a baking sheet and roll over the meat to even it out. Bake for 10 minutes at 350 degrees. Add the diced onions to the edges of the baking sheet and bake for an additional 15 minutes. Spoon the onions over the meat and top with cheese slices. Bake for 10 minutes before topping the sheet with the top of the dinner rolls. Bake for 5 final minutes. Assemble the sliders.
