01 - In a mixing bowl, whisk together eggs, milk or cream, salt, black pepper, and smoked paprika until fully incorporated.
02 - Melt butter in a nonstick skillet over medium heat. Add red bell pepper and green onion; cook until vegetables are softened, about 2 minutes.
03 - Pour the egg mixture into the skillet. Gently scramble until eggs are softly set, approximately 2 to 3 minutes. Remove from heat and reserve.
04 - On a cutting board, lay one tortilla flat. Evenly distribute half of each cheese over the surface. Arrange scrambled eggs, chicken, and sautéed vegetables on top, then sprinkle remaining cheese over the filling.
05 - Place the second tortilla over the filling to form a sandwich.
06 - Heat a large skillet or griddle over medium heat. Carefully transfer the filled tortilla to the skillet. Cook for 2 to 3 minutes per side, pressing lightly with a spatula, until golden brown and cheese is melted.
07 - Remove from skillet and allow to rest for 1 to 2 minutes. Cut into wedges and serve immediately.
