Heat 1 tablespoon of avocado oil in a large skillet over medium heat.
Add chopped onion and sauté until translucent, about 3 minutes.
Add ground turkey and cook, breaking it up with a spatula, until browned.
Mix in chopped kale and cook until wilted.
Season with salt, pepper, onion powder, garlic powder, paprika, chili powder, and cumin powder. Stir well to combine.
Remove the filling from the skillet and set aside.
Add remaining 1 tablespoon of avocado oil to the skillet.
Place a tortilla in the pan. Arrange 2 slices of cheddar cheese on half of the tortilla.
Spoon half of the turkey mixture over the cheese.
Fold the tortilla over to cover the filling.
Cook for 2–3 minutes per side until golden brown and cheese is melted.
Repeat with the second tortilla and remaining filling.
Slice into wedges and serve warm.
