Heat the soup in a saucepan over medium heat until hot.
Heat the butter in a skillet over medium heat. Place the tortilla in the skillet. Place the cheese and the jalapeño (if using) on half of the tortilla. Fold the tortilla in half over the filling. Cook until golden brown and crispy on both sides and the cheese is melted.
Cut the quesadilla in half. Top the soup with Mexican crema, sliced green onion and chile pepper, if desired, and serve with the quesadilla.
