Melt 1 tablespoon of butter in a large frying pan over medium-low heat.

Once melted, add the olive oil and onions, stirring occasionally, until they are deep golden brown and caramelized – about 30 minutes. Add a pinch of brown sugar and season well with salt and pepper. Remove from heat and set aside.

Lay 4 tortillas flat and divide the cheese evenly on all four tortillas. Top with caramelized onions and pulled pork. Top with a second tortilla.

Heat a large skillet over medium heat. Add a 1/2 tablespoon of butter to the pan and let melt. Add quesadilla and cook for about 2-4 minutes, until golden brown on the bottom. Carefully but swiftly flip the quesadilla, and cook for another 2-4 minutes on the other side, or until the cheese is melted.

Repeat the process until all 4 quesadillas have been cooked. Cut each quesadilla into 4 wedges and serve with a drizzle of bbq sauce.
