I am updating this review due to the fact that when reading it I realized I failed to mention that I was also out of lasagna noodles. Not wanting to go to the store I used farfalle which I cooked and layered as you would noodles. Carrol, You should be very proud of your creation. It is wonderful! I used ricotta instead of cottage cheese and sauted the onion and mushrooms in olive oil instead of the butter. Couldn't keep myself from sampling the pesto while putting it together. Delicious!
