Very good! Easy with a food processor, lol. I cooked it 60 minutes & there were a few bites that would have benefited from more time. Love the crunchy top! Family wished there was more cheese. Jeez, I used an entire block (8oz ) even though it was more than 2c. I subbed a large shallot for the red onion. No leftovers! Thank you, Rita! Made for winner of Sun & Spice Event veggie finder. :)
