Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Slice the jalapeños in half lengthwise and use a spoon to carefully scrape out the seeds and white membranes.
In a non-stick skillet over medium-high heat, cook the ground turkey until browned and no longer pink, breaking it into small crumbles.
In a medium mixing bowl, combine the cooked turkey, Greek yogurt, softened Neufchatel cheese, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Stir the mixture until the cheese and yogurt are well incorporated and the turkey is evenly coated.
Spoon the turkey filling into each jalapeño half, mounding it slightly and pressing firmly to ensure it stays in place.
Arrange the stuffed jalapeños on the prepared baking sheet and bake for 15 to 18 minutes, or until the peppers are tender and the filling is hot.
Remove from the oven and sprinkle with freshly chopped chives before serving.
