I read the reviews here before I made this - only real changes were a little bit of tomato puree, little more spices (I'm usually a little heavy handed with them anyway), and no ricotta. (I'm a college kid, I'd never finish the rest of it)
Mine turned out really good! It is slightly on the watery side, but I don't really see it as a problem - it's just a chunkier sauce with a little thinner stuff with it. If it came out the same way next time I would probably dump the pasta back into the sauce pot and mix it all up - that would probably solve any wateriness problems.
But overall, mine is delicious. It's a good way to incorporate some veggies into your pasta dinner.
