For some reason, I had forgotten about this recipe and have not made it in quite a while. It is a good twist on meatloaf in general. Both my husband and kids love it. It takes a little bit of time in the initial prep work, but well worth the effort.
1 1/2 lbs ground beef (I used 1 1/4 lbs this time)
1/2 cup Italian or plain breadcrumbs
1 jar pasta sauce
2 cups shredded mozzarella cheese
1/4 cup diced onion
