Preheat your oven to 400°F and line a baking sheet with parchment paper.
Slice the jalapeño peppers in half lengthwise and use a spoon to carefully remove the seeds and ribs.
In a non-stick skillet over medium heat, add the olive oil and ground turkey, seasoning with the sea salt, black pepper, and garlic powder.
Cook the turkey until fully browned and crumbled, then remove from heat to cool slightly.
In a medium mixing bowl, combine the cooked turkey, Greek yogurt, cream cheese, and shredded cheddar cheese until well incorporated.
Spoon the turkey mixture into each jalapeño half, pressing down firmly to pack the filling.
Sprinkle the almond flour over the top of each stuffed pepper to create a crust.
Place the peppers on the prepared baking sheet and bake for 15 to 18 minutes until the peppers are tender and the topping is golden brown.
