- Preheat your oven to 400°F (200°C). 
- In a large bowl, mix ground beef, breadcrumbs, egg, garlic powder, salt, pepper, cheddar cheese, and bacon. 
- Form into meatballs—somewhere between golf ball and ping pong ball size. 
- Place them on a baking sheet lined with parchment paper and bake for 15-18 minutes until cooked through. 
- While they bake, simmer BBQ sauce and bourbon in a small saucepan for about 5 minutes to thicken slightly. 
- Toss baked meatballs in the bourbon BBQ sauce until nicely coated. 
- Split your hoagie rolls, toast them in a skillet with butter if you’re feeling fancy. 
- Load up each roll with saucy meatballs, extra cheese if desired, and maybe a little more bacon. No one’s judging. 
- Serve warm with napkins nearby. You’ll need them.
