 - 1 lb ground beef
 - 8 slices of rye bread

 - 1 large onion, thinly sliced
 - 4 tbsp butter, plus more for spreading
 - Salt and pepper to taste

- Grill the Sandwiches:
 
- In a clean skillet over medium heat, grill the sandwiches until golden brown and the cheese is melted, about 3-4 minutes per side.
 
- Serve:
 
- Once cooked, cut the patty melts in half and serve hot.
