In a mixing bowl, combine the ground chicken with paprika, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix until fully incorporated.
Place a sheet of parchment paper on a flat surface and add half the chicken mixture on top. This recipe makes 2 chicken hot pockets so use half the ingredients for everything.
Lay a second sheet of parchment over the chicken and roll it into a thin rectangle using a rolling pin.
Remove the top sheet of parchment and add half the toppings to one half of the chicken rectangle (pesto, spinach, red onion, sundried tomatoes, and mozzarella cheese).
Fold the parchment over so the chicken layer covers the toppings, forming a sealed pocket.
Press the edges with a fork to secure and fully seal the hot pocket.
Sprinkle half the parmesan over the top, gently pressing to help them adhere.
Transfer to the air fryer and cook at 375°F for 12–15 minutes, or until fully cooked through.
Repeat the process for the second hot pocket. Slice and serve warm.
