• Preheat the oven to 400 degrees.
• Line a baking tray with parchment paper and set it aside.

Prepare the BBQ sauce:

• In a large saucepan, add the butter, onions, celery and garlic. Sweat until the onions and celery begin to brown.
• Next, you will add everything else including, the green pepper, ketchup, dry mustard, water, tomato paste, apple cider vinegar, lemon juice, Worcestershire sauce, brown sugar, salt, cracked black pepper and liquid smoke. Simmer over low heat for 30 – 35 minutes.

Prepare the meatballs:

• In a large mixing bowl, combine the ground chicken, breadcrumbs, egg, milk, parmesan cheese, onion powder, garlic powder, salt, pepper, and dried parsley. Mix until well combined. Don't overwork the meat.
• Roll the chicken mixture into evenly sized meatballs. I was able to get 12 medium sized meatballs from my mixture. Place the meatballs on the prepared baking tray and cook them for 25-30 minutes or until they reach 165 degrees Fahrenheit.
• Make sure to turn them halfway so they do not get too brown on one side. Cooking time will depend on the size of your meatballs.
• Remove the meatballs from the oven and toss them in the BBQ sauce. Serve warm.
