In a small bowl, combine 1 can black beans that have been rinsed and drained with 1 can green chiles. Stir until well mixed.
Pour a small amount of 2 cups red enchilada sauce into the bottom of a 9x13 baking dish. Pour the remaining enchilada sauce into a separate bowl, then dip all 8 corn tortillas in the enchilada sauce.
Fill each tortilla with approximately ¼ cup of the black bean mixture and a small amount of the 3 cups shredded Monterey Jack cheese. Roll each tortilla up and place it seam side down in the baking dish.
Continue filling and rolling the tortillas until all 8 corn tortillas are in the pan. Pour the remaining enchilada sauce over the top and sprinkle with the remaining Monterey Jack cheese.
Then bake the enchiladas for 15-20 minutes until the cheese is melted and slightly golden brown.
Top with ½ cup chopped cilantro and 4 sliced green onions before serving. Serve warm and enjoy.

Notes
I used canned black beans in this recipe but you can make them with homemade black beans as well. Also, flour tortillas can be used instead of corn if you prefer. Refrigerate leftover enchiladas in an airtight container for up to 5 days.
