Method
- Heat a skillet over medium heat and add ground beef. Brown in batches, avoiding steam, about 5–7 minutes per batch
- Add sliced onions to the skillet with the beef. Cook until onions caramelize, 8–10 minutes
- Lay 2 slices of rye bread on a plate. Top each with 1 Swiss and 1 cheddar cheese slice. Spoon beef mixture over cheese
- Mix mayonnaise, ketchup, relish, and Worcestershire sauce in a small bowl
- Butter 1 side of each bread slice. Place sandwiches butter-side down in the skillet. Add 2–3 tablespoons of the sauce to each sandwich
- Cook over medium heat until bread is toasted and cheese is melted, 2–3 minutes per side
- Repeat with remaining ingredients
