Preheat the oven to 425°F.Line a rimmed baking sheet with foil and spray with cooking spray.In a large bowl mix the turkey, bacon, apples, onions, feta, barbecue sauce (or syrup), salt, pepper, garlic powder, and optional poultry seasoning together until combined. (Katie says she uses her hands to mix well.)Scoop ¼ cup of the meat mixture and form into 10 mini sliders.Place the sliders on the prepared baking sheet. Bake for 30 to 35 minutes or until the centers of the burgers are no longer pink or a meat thermometer reaches a minimum of 165°F.Remove the baking sheet from the oven and let the burgers rest for 5 to 10 minutes.Serve on a whole grain bread, sandwich thin, or lettuce wrap. (I used ½ of a sandwich thin with each slider for the 4 smart point per serving total)
