I am always on the search for a great/easy/cheap meatball substitute. I have found the best one thus far! Sarah Kramer, I think in Vegan A Go-Go (I cook from all of them so much I can't keep it straight!) has a winner winner tofu dinner!
Slightly messy prep, copious cheap wine :)
I cooked them with no oil to make it a little healthier.
Atop a pile of quinoa pasta and waiting for some yummy marinara sauce!
