Very smart base recipe! Polenta works wonderfully as a substitute for noodles, and makes the meal lighter and let the other ingredients used stand with their own flavors. I did mine in this order: layer of polenta, layer of pesto, layer of fresh spinach, layer of onions (1/2 of a white) and fresh tomatoes (about 7 romas), layer of ricotta cheese, layer of sauce, next layer of polenta,layer of mozzarella, then topped with pinenuts and fresh parmesean! It was fantastic and I may never eat noodle lasagna again!
