Preheat oven to 350°F.
In a large mixing bowl add the ground beef and all spices. Mix together.
Using your hands, roll meatball mixture into golf ball size balls and place in a 9x11 baking dish. Will make 36 meatballs.
Bake for 30-35 minutes or until meatballs are cooked through.
While meatballs are cooking make the sauce. In a high-speed blender add the bbq sauce and fresh blueberries. Blend on medium for 20 seconds or until blueberries are chopped to small pieces.
Remove meatballs from oven, place in a slow cooker. Pour bbq sauce and blueberry mixture over the top. Stir to evenly coat meatballs. Turn slow cooker on low. Serve once heated through.
Store leftovers in a covered glass container in the fridge for up to 5 days.
