Creating Patty Melts with Charred Scallion-Chipotle Mayo is straightforward if you follow these simple steps:

1. Prepare the Mayo: In a small bowl, combine mayonnaise and chopped chipotle in adobo sauce. Mix well and set aside.
2. Char the Scallions: In a skillet over medium heat, add a teaspoon of butter. Once melted, add chopped scallions and sauté until charred, about 2-3 minutes. Remove from heat and set aside.
3. Form the Patties: In a mixing bowl, season the ground beef with salt and pepper. Form into two equal-sized patties.
4. Cook the Patties: In the same skillet, add the beef patties. Cook for about 4-5 minutes on one side, then flip and place a slice of Swiss cheese on top. Cook for an additional 4-5 minutes until cooked through and cheese is melted.
5. Toast the Bread: While the patties are cooking, butter one side of each slice of rye bread. In another skillet, toast the bread until golden brown, about 2-3 minutes on each side.
6. Assemble the Patty Melts: Spread the chipotle mayo on the non-buttered side of one slice of toasted bread. Place the cooked patty with melted cheese on top, followed by the charred scallions. Top with another slice of toasted bread, mayo side down.
7. Finish Cooking: Return the sandwich to the skillet, cooking until both sides are golden brown and crispy, about 2-3 minutes per side.
8. Slice and Serve: Remove from the skillet, slice in half, and serve hot.
