In a small bowl, mix the cream, ground paprika, lemon juice, salt, and pepper.
In another bowl, mix the cream cheese and goat cheese. Spread this mixture on the tortillas. On half of each tortilla, place the salmon, shallots, bell pepper, and avocado.
Place the quesadillas on a pan greased with olive oil. Fry until the cheeses melt, about 1-2 minutes on each side. Serve with the sauce prepared earlier and sprinkled with cilantro.
