Combine first 5 ingredients; spread about 3/4 cup cheese mixture onto each of 4 tortillas, leaving a 1/2-inch border. Top each with a tortilla, pressing gently to secure.
Place tortillas on a baking sheet coated with cooking spray; cover with foil.
Bake at 350 for 25 minutes or until cheeses melt.
Serve with Green-Chile Salsa; garnish with cilantro sprigs, if desired.
