In a mixing bowl, combine ground beef, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix gently and let rest for 10 minutes.

Preheat your grill or skillet over medium-high heat until hot enough that a drop of water sizzles.

Divide the beef mixture into eight portions, shape into patties about ½ inch thick.

Brush the grill or skillet with olive oil, add patties, and cook for 2-3 minutes without moving.

Flip the patties and cook for another 2-3 minutes until desired doneness; then let them rest.

Brush one side of each tortilla with melted unsalted butter for better crispiness.

Assemble the quesadilla: place buttered tortilla on grill, fill half with cheese, beef patty, onions, pickles, and tomatoes, then fold.

Grill the quesadilla for 2-3 minutes on one side, flip carefully, and grill for another 2-3 minutes until golden.

Repeat with remaining ingredients, let rest for a minute, slice into wedges, and serve warm.

Garnish as desired and enjoy!
