- 2 burger patties
- 4 slices of Rye bread
- 1/2 large white onion sliced
- 2 slices of Swiss cheese
- Mayo
- 2 tbs butter
2. Saute onions over medium heat in butter slowly until tender, brown, and sweet. This takes about 15-20 minutes and requires you continue to stir around and mix up.
3. Once onions and burger patties are finished the fun part begins. Spread some butter one side of each piece of rye bread.
4. Just like making a grilled cheese, lay one slice of bread, butter side down on hot griddle. Top with burger patty, some caramelized onions, and Swiss.
5. Quickly spread some mayo on the non buttered side of another piece of bread and place on top.
6. Cook on both sides like a grilled cheese until brown and crisp.
