Spoon half of vegetable-bean mixture over tortillas; sprinkle with 2/3 cup of the cheese. Spoon half of remaining sauce mixture over cheese. Repeat layers, reserving 2/3 cup cheese for top. Top with reserved 1/3 cup enchilada sauce. Cover with foil.

Bake at 375°F. for 30 to 35 minutes or until thoroughly heated. Uncover; sprinkle with reserved 2/3 cup cheese. Bake, uncovered, an additional 5 minutes or until cheese is melted. Let stand 10 minutes before serving. Sprinkle with cilantro.
