7. Spread burger sauce evenly on both the top and bottom halves of the rolls.
8. Layer the bottom half with cooked patties, caramelized onions, cheese slices (tear if needed to fit), and dill pickles.

10. Cover with foil and bake for 15 minutes, or until cheese is melted and rolls are warmed through.
