In a large bowl, combine the ground turkey, breadcrumbs, chopped parsley, grated parmesan cheese, egg, garlic powder, onion powder, salt, and pepper. Mix gently until just combined, being careful not to overmix.
Shape the mixture into small meatballs about 1 to 1.5 inches in diameter, yielding around 20 meatballs. Place them on a baking sheet lined with parchment paper or a silicone mat.
Preheat the oven to 375°F (190°C). Bake the meatballs for 20-25 minutes until cooked through and golden brown. Alternatively, cook them in a skillet over medium heat with a bit of oil, turning occasionally.
While the meatballs bake, combine the peach preserves, apple cider vinegar, and smoked paprika in a small saucepan over medium heat. Stir frequently until the preserves melt and the sauce thickens slightly, about 5-7 minutes. Remove from heat.
Toss the cooked meatballs gently in the warm peach-bourbon BBQ sauce until evenly coated.
Slice the slider buns in half. Place 2-3 sauced meatballs on the bottom half of each bun. Sprinkle crumbled turkey bacon on top, cover with the top bun half, and serve immediately.
