Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Slice the jalapeños in half lengthwise and use a small spoon to carefully scrape out the seeds and white membranes.
In a medium mixing bowl, combine the shredded cooked chicken breast, Greek yogurt, shredded cheddar cheese, garlic powder, onion powder, and smoked paprika.
Spoon the chicken mixture into each jalapeño half, pressing it down firmly to ensure it is well-packed.
In a small shallow dish, mix the almond flour, sea salt, and black pepper, then stir in the olive oil until the mixture resembles wet sand.
Press the stuffed side of each jalapeño into the almond flour mixture to create a thick, even crust.
Arrange the poppers on the prepared baking sheet and bake for 15 to 18 minutes until the peppers are tender and the topping is beautifully golden and crisp.
