Step 1

For the meatballs: In large bowl, mix together the meatball ingredients until combined evenly (I use my hands). Roll into 40 balls (about 1 1/2-2 inches).

Step 2

Space evenly on prepared baking sheet. Bake in a 425 degree oven for 20-25 minutes.

Step 3

For the casserole:  Pour half of the spaghetti sauce in the bottom of a 2qt baking dish. Top with meatballs. Pour remaining sauce over meatballs. Top with shredded parmesan and mozzarella.

Step 4

Cover with foil and bake in a 375 degree oven for 30 minutes. Remove foil and bake an additional 5 minutes, until cheese is melted.

Step 5

Serve as is, or with a pile of pasta. Also great on a sub sandwich!
