Preheat oven to 350°F and set aside a 9x13-inch baking pan.
To a large bowl, add shredded chicken, drained black beans, 1/2 cup shredded cheese, and 2/3 cup enchilada sauce. Stir.
2 cups shredded cooked chicken, 15 ounce can black beans, 1.5 cups shredded Mexican blend cheese, 15 ounces red enchilada sauce
Place tortillas on a flat surface and fill with enchilada filling. Tightly roll tortillas over the filling, then place them seam-side down in the baking pan. Top enchiladas with remaining enchilada sauce, then with remaining cheese.
