- Combine thawed meatballs and chopped onion in your slow cooker.
 - Add brown sugar, onion soup mix, and beer to the slow cooker.

 - When ready to serve, place 6 meatballs on each hoagie roll bottom.
 - Sprinkle each with ¼ cup of shredded Swiss cheese.
 - Place under broiler for 2-3 minutes until cheese is melted and bubbly.
 - Top with the other half of the roll and serve immediately.
 
Notes
For deeper flavor, try using a dark German beer in this recipe. If serving for a crowd, you can keep the meatballs warm in the slow cooker and let guests assemble their own sandwiches.
These meatballs can also be served over mashed potatoes for a gluten-free option. Leftovers will keep refrigerated for up to 3 days and the flavor actually improves overnight.
