In a mini food processor, combine half of a ripe avocado, 1/4 cup of sour cream, one tablespoon of fresh lime juice, 1/4 cup of packed cilantro leaves, and 1/2 teaspoon of kosher salt. Add two tablespoons of water and blend until creamy. Adjust seasoning if needed and refrigerate.
Heat two teaspoons of avocado oil in a large non-stick pan over medium heat. Add 8 ounces of lean ground turkey, 2 1/2 teaspoons of taco seasoning, and 1/3 cup of chopped onion. Cook for 4-5 minutes until browned.
Stir in 3/4 cup of drained black beans, 4 ounces of green chiles, the remaining taco seasoning, and 2 tablespoons of water and finely chopped cilantro. Simmer uncovered for 15 minutes.
If there's excess liquid, increase heat to medium and cook for a few more minutes until thickened.
Preheat oven to 425 F. Spray a baking sheet with cooking spray. Lay out 6 tortillas and sprinkle 1/4 cup of cheese on each.
Spoon 1/4 to 1/3 cup of turkey mixture onto one half of each tortilla. Fold carefully.
Bake for 1-2 minutes until cheese melts. Fold tortillas in half, brush with avocado oil, and bake for another 10-12 minutes until golden brown and crispy.
