Toss Buffalo Chicken: In a medium bowl, combine shredded halal chicken, buffalo pepper sauce, melted butter, garlic powder, and onion powder. Stir until all meat is generously coated in the fiery sauce.
Assemble Quesadillas: Lay flour tortillas flat on a clean board. On one half of each tortilla, layer shredded Monterey Jack, a generous portion of buffalo chicken, sliced green onions, and top with sharp cheddar (cheese on both bottom and top locks the quesadilla together). Fold other half over to create half-moons.
Preheat Skillet: Heat a large cast-iron skillet or nonstick griddle over medium heat. Lightly brush the pan with a touch of butter or avocado oil.
Griddle Until Crispy: Place the folded quesadilla into the skillet. Cook for 3 to 4 minutes on the first side until golden brown, crispy, and blistered. Gently press with a spatula.
Flip & Melt: Carefully flip and cook for another 2 to 3 minutes until both sides are deeply golden and the interior cheeses are fully melted and bubbling.
Rest & Slice: Transfer quesadilla to a cutting board and let rest for 1 minute so the cheese settles. Slice into 3 triangular wedges using a pizza wheel or sharp chef knife.
Garnish & Serve: Drizzle with extra buffalo hot sauce and creamy ranch, scatter fresh scallions over top, and serve immediately with cool dips and fresh lime.
