Thank you for this gorgeous recipe! I made this last night with great results. I had no Zucchini, so I used a large field mushroom in its place and no TMX stock, so I used normal beef stock and a bit of water. I had heaps of tomatoes, so I used them in place of the canned ones.
Perhaps because of my alterations, my 'balls' were very light and I was concerned they would collapse with the pasta (I only had spirals) so I browned them in the oven for 10 mins before serving and they were pretty much perfect.
My husband has been very dubious about my TMX meals after a few disasters. This one however, he had seconds and has taken leftovers for lunch too!
This recipe makes a lot of meatballs and sauce. I would say you could easily feed an average family of four. I would add a garlic bread or veg with it if I was feeding hungry teens or more than one man though.
I am looking forward to making this again soon
