In a large cast iron grill or griddle pan, cook the vegetables on high heat until they're slightly crispy and well-browned.

Remove the vegetables from the pan. Add the thinly sliced ribeye meat and sear quickly on both sides until just cooked through.

Mix the Worcestershire sauce into the ground beef, handling minimally to maintain tenderness. Form into four equal patties, then press your thumb into the center of each patty to create an indent (this prevents the patty from bulging during cooking).

Season patties with kosher salt and pepper to taste. Cook on high heat for 3 minutes on the first side.

Flip the patties, immediately place a slice of Provolone cheese on top of each, and cook for an additional 3 minutes for medium doneness.

Remove the patties from the pan and reduce heat to low. Press the bun halves cut-side down into the pan and toast until lightly browned, about 1-2 minutes.

Spread mayonnaise on both bun halves. On the bottom bun, layer lettuce (if using), the beef patty with cheese facing up, a portion of the ribeye steak, cooked peppers and onions, and tomato slices (if using). Top with the upper bun half and serve immediately.
