Add black beans, green chiles, shredded cheese and seasoning to a medium mixing bowl. Use a fork and mash all ingredients together.
Evenly divide mixture onto tortillas. Spread mixture over each tortilla, roll tightly, lightly spray each side with nonstick cooking spray or brush with olive oil, and place seam side down on parchment lined cookie sheet or nonstick baking dish. Don’t allow flautas to touch so that they get crispy on all sides.
Bake approximately 20-25 minutes, or until flautas are hot and crispy, turn over about halfway. If desired, top flautas with fat free Greek yogurt.
