Meatball Submarine Casserole

We were hosting a bunch of friends, and after a comedy of errors, I had to come up with a new plan for dinner. Turns out that much-loved meatball subs are even better as a hearty casserole—so delicious! —Rick Friedman, Palm Springs, California

    My husband and I both really liked it. It was a hit!! I did make one change, I used frozen garlic toast instead of sourdough bread. I also used the entire jar of sauce.

    This was a pretty basic recipe, but easy to make and my husband and I both liked it. I didn't want a part of a bottle of sauce left so I used the whole bottle and added a little more bread. I think it needed that sauce though. I also added at least twice as much cheese. My husband would have definitely said it needed more cheese if I would have put the recipe amount. :)
