For large tortillas: Divide the smoked salmon, onion, cilantro, dill, jalapeno and cheese evenly among the tortillas, placing the toppings only on half of the tortilla. Bake the open tortillas at 400°F until the cheese has melted. Fold the uncovered half of the tortilla over the toppings and cut into 4 wedges to serve.
For small tortillas: Divide the smoked salmon, onion, cilantro, dill, jalapeno and cheese evenly among the half of the tortillas. Bake the tortillas at 400°F until the cheese has melted. Place the other half of the tortillas on top of the toppings and continue to bake for 3-5 more minutes until the second tortilla has warmed through. Cut each quesadilla into 4 wedges to serve.
Serve with sour cream, plain Greek yogurt or your favorite salsa.
