In a large bowl, combine the ground beef with salt, black pepper, and Worcestershire sauce.
Divide the meat into four equal portions, then shape them into patties.
Heat a skillet or grill to medium-high heat and brush lightly with olive oil.
Cook the patties for about 3-4 minutes per side, until nicely browned.
During the last minute of cooking, place a slice of Pepper Jack cheese on each patty and let it melt.
In another skillet, melt the butter and sauté the chopped onions over medium heat until golden brown and caramelized.
Halve the hamburger buns and toast them lightly in a dry skillet or on a grill.
Spread mayonnaise and Dijon mustard on the bottom half of each bun, then top with a lettuce leaf.
Place the cheesy beef patty on top, then sprinkle with the caramelized onions.
Add the tomato slices, pickled cucumber slices, and chopped jalapeño pepper for a spicy kick.
Top with the other half of the bun and serve immediately with french fries or a fresh salad.
