My husband and I really like French onion soup but I wanted to do something different with it. This is what I came up with. We both really enjoyed this recipe as a sub and the leftovers with noodles as I have added at the end of the recipe. I hope everyone that tries this enjoys as much as we do.

This sub is super easy and yummy. The onion and beef flavors soak into the meat and create fantastic meatballs. We melted the cheese in the oven along with toasting the bun like Nelda suggested and they were amazing. Your friends will think you spent some time making these (it'll be our secret about how easy they are). Between the gooey melted cheese and the caramelized onions, this is better than any sub you can buy at the store. We took some of the extra broth and served it on the side... so good. Also, we put 4 meatballs on each sub.
