In a large bowl, combine the cooked macaroni and cheese, chopped crispy bacon, and ranch dressing. Stir thoroughly until the mixture is creamy and thick enough to mound without running.

Place one flour tortilla flat on a clean surface. Spread a generous portion of the mac and cheese mixture over one half of the tortilla, maintaining a clear edge. Evenly top with shredded cheddar and mozzarella cheese, then fold the tortilla in half to form a half-moon shape.

Heat a large skillet over medium heat and add olive oil to coat the base. Once shimmering, carefully place the folded quesadilla in the pan. Cook for three to four minutes on each side, pressing gently to promote even browning and a golden, crisp crust.

Remove the quesadilla from the skillet and transfer to a cutting board. Allow it to rest for one minute to let the cheese set slightly. Slice into wedges and garnish with chopped green onions. Serve immediately for optimal gooey texture and crispness.
