So here is my attempt.
The Sauce - made the default recipe but added a bit more garlic, pepper, and red chile powder. Sorry the image is a bit blurry.

The Meatballs - just followed the default recipe as best as I could with what I had on hand.

This is the final product. It was good - the teenage kids even liked it.

Thanks for the course. I learned a lot and had a great time making the meatballs and sauce.
