Preheat the oven to 350 degrees F.
In a large pan, cook ground turkey over medium heat. Season with taco seasoning and continue to saute until fully cooked through. Add black beans and stir. Cook until heated through. Add about 2 tablespoons of cheese and stir until melted. Remove from the heat and set aside.
Place tortillas on a microwave safe plate and cover with a towel or paper towel. Warm in the microwave for 1 minute or until heated. Set aside.
In an 8x11 casserole dish, pour ½ cup of enchilada sauce and spread evenly. This helps avoid sticking later.
Add ¼ cup of the black bean and turkey mixture to each tortilla, roll, and place in the casserole dish with the seam side down. Continue doing this until all tortillas are used.
Pour the remaining black bean mixture over the rolled enchiladas and top with remaining enchilada sauce. Sprinkle remaining cheese evenly over the top.
Bake at 350 degrees for 25-30 minutes or until cheese is golden and filling is bubbly. Serve with optional toppings and enjoy!
