01 - In a small mixing bowl, whisk the eggs with milk or cream, salt, black pepper, and smoked paprika until fully blended.
02 - Heat a nonstick skillet over medium heat and add the unsalted butter. Sauté the red bell pepper and green onion until softened, about 2 minutes.
03 - Pour the egg mixture into the skillet and gently scramble until softly set, approximately 2–3 minutes. Remove from heat and set aside.
04 - Place one flour tortilla on a clean work surface. Sprinkle half of each cheese evenly, then layer with scrambled eggs, cooked chicken, and sautéed vegetables. Top with remaining cheese.
05 - Cover the filling with the second tortilla, pressing gently to secure.
06 - Heat a large nonstick skillet or griddle over medium heat. Transfer quesadilla and cook for 2–3 minutes per side, applying light pressure with a spatula, until golden brown and cheese is melted.
07 - Remove from heat, let rest for 1–2 minutes, then slice into wedges and serve immediately.
