Heat a cast-iron skillet or griddle over medium-high heat for about 5 minutes.

Take a quarter of the ground beef and press it onto one half of a flour tortilla, seasoning with salt, pepper, and garlic powder.

Place the tortilla beef-side down onto the hot skillet and cook undisturbed for 2-3 minutes until edges are crispy.

Once flipped, sprinkle cheese generously over the beef and fold the tortilla in half. Grill for an additional 1-2 minutes.

Let the quesadilla rest for a minute, then slice into triangles.

Serve with optional toppings like pickles and diced onions.
