Make the Avocado Sauce: In a blender, combine half a ripe avocado, sour cream, fresh lime juice, chopped cilantro, salt, and a splash of water. Blend until smooth and creamy, adjusting the consistency with more water if needed. Refrigerate while preparing tacos.

Cook the Turkey: Heat avocado oil in a skillet, sauté onions until translucent. Add ground turkey, cook until no longer pink, then stir in taco seasoning and cook for an additional 2 minutes.

Combine Filling: Stir in drained black beans and green chiles. Simmer on low heat for about 10-15 minutes, stirring occasionally to prevent sticking.

Assemble Tacos: Preheat the oven to 425°F (220°C). Place cheese on one side of each tortilla, scoop turkey filling onto cheese side, and fold tortillas.

Bake Tacos: Arrange tacos on a baking sheet, brush tops with avocado oil. Bake for 10-12 minutes until golden and crispy.

Serve: Remove from the oven, let cool for a minute, and serve with avocado sauce for dipping.
