01 - Heat a large skillet over medium heat. Add sliced sausage and cook for 3–4 minutes, until browned. Remove and set aside.
02 - In the same pan, add peppers and onion. Sauté for 5 minutes, until softened. Sprinkle with Cajun seasoning, smoked paprika, salt, and pepper. Stir well.
03 - Return the sausage to the skillet, mix, and cook for 2 more minutes. Remove the mixture to a bowl. Wipe the skillet clean.
04 - Melt 1/2 tbsp butter in the skillet over medium heat. Place a tortilla in the pan, sprinkle a quarter of the cheese evenly over half of it, then spread a quarter of the sausage and veggie mixture over the cheese. Fold the tortilla to enclose the filling.
05 - Cook for 2–3 minutes per side, or until golden brown and cheese has melted. Repeat with remaining tortillas, butter, cheese, and filling.
06 - Slice each quesadilla into wedges and serve hot.
