01 - In a small mixing bowl, whisk eggs with milk or cream, salt, black pepper, and smoked paprika until fully blended.
02 - Heat a nonstick skillet over medium heat. Add unsalted butter, then sauté red bell pepper and green onion until softened, about 2 minutes.
03 - Pour the whisked egg mixture into the skillet. Stir gently until eggs are softly set, approximately 2–3 minutes. Remove from heat and set aside.
04 - Lay one flour tortilla on a clean work surface. Sprinkle half of each cheese over the surface. Evenly distribute the scrambled eggs, chicken, and sautéed vegetables. Top with the remaining cheese.
05 - Position the second flour tortilla on top. Heat a large skillet or griddle over medium heat. Carefully transfer the filled tortilla to the pan.
06 - Cook for 2–3 minutes per side, pressing gently with a spatula, until the exterior is golden brown, the cheese is melted, and the quesadilla is crisp.
07 - Remove from heat. Let rest for 1–2 minutes, slice into wedges, and serve immediately.
