Combine scallions, turkey, beans and 1/2 cup enchilada sauce.
Fill each tortilla with 1/4 of turkey-bean mixture. Fold in sides and then top and bottom of tortilla to completely enclose filling. Place seam-side down in a 9 x 13-inch baking dish.
Pour remaining 1/2 cup enchilada sauce over top of enchiladas and top with cheese. Cover pan and bake until heated through and cheese is hot and bubbly, 20 minutes.
