Place the uncooked bacon into a food processor and process for about 1 minute or until finely ground. Add in the onion and process until finely chopped and mixed in.

Spoon the bacon and onion mixture into a large bowl. Add ground beef, breadcrumbs, parsley, egg, chili powder, and salt. Stir to combine.

Scoop out the meat mixture and roll into balls using your palms; this should make about 24 1-inch meatballs.

Heat oil in a large saucepan over medium heat. Place the meatballs into the saucepan and cook, turning every couple minutes to ensure all sides cook evenly. Cook for about 8-10 minutes until fully cooked.

Remove the meatballs and set aside. Remove the pan from the heat and pour out the excess grease.

Add the barbecue sauce, beef broth, and bourbon to the saucepan and return to heat. Stir to mix the sauce together.

Add in the meatballs and allow them to simmer in the sauce for at least 10 minutes.
