I had bought two big frozen lasagnes ahead of time, one with meat and cheeses and one "vegetable lasagne." That looked interesting. It was also very interesting what was left after the seven of us had our fill:
The one on the left is the vegetable lasagne--barely one square left over. On the right: 3/4 of the meat/cheese lasagne. We all agreed the vegetable lasagne is a winner!
It's Stouffer's Party Size frozen Vegetable Lasagne. I bought it at the local Walmart. Highly recommended!
