# How to Make:
01 - In a medium bowl, gently combine ground beef with salt, pepper, and garlic powder until just incorporated, being careful not to overwork the meat.
02 - Preheat a flat griddle or heavy skillet over medium-high heat. Add 1 tablespoon vegetable oil and coat the surface evenly. Place sliced onion on one side of the griddle and cook, stirring occasionally, until golden and softened, approximately 5 minutes. Transfer to a plate and reserve.
03 - Divide beef mixture into 8 equal portions and roll each into a loose ball. Place 4 beef balls onto the hot griddle with even spacing. Immediately press each firmly with a heavy spatula or burger press to create thin patties approximately 4 inches in diameter.
04 - Allow patties to cook undisturbed until edges are deeply browned and juices bubble up on the surface, approximately 2 minutes. Season tops with a pinch of salt and pepper.
05 - Flip each patty and immediately top with 1 slice of cheddar and 1 slice of American cheese. Cook until cheese melts and edges crisp, approximately 1 minute more. Transfer patties to a plate.
06 - Wipe the griddle clean and reduce heat to medium. Brush both sides of each tortilla lightly with melted butter. Whisk together mayonnaise, Dijon mustard, and Worcestershire sauce in a small bowl.
07 - Place a tortilla on the griddle. Layer 2 cheesy patties side by side in the center, sprinkle with cooked onions, and drizzle with prepared sauce. Top with a second tortilla.
08 - Cook until the bottom tortilla achieves a golden, crisp texture, approximately 2 minutes, pressing gently with a spatula. Flip and cook the opposite side until golden, approximately 2 minutes more.
09 - Transfer quesadilla to a cutting board and allow to rest for 1 minute. Slice into wedges using a sharp knife or pizza cutter.
10 - Repeat assembly and cooking process with remaining ingredients to prepare the second quesadilla. Serve hot with desired garnishes including pickles, cilantro, salsa, or sour cream.
