I'm making a lasagna this weekend - the vegetarian option one.
I've made a lot of lasagnas - many good ones. But I am looking for some new ones to try. I am not a huge fan of the eggplant or mushrooms. I have used beans, squash, various cheeses and herbs. I've done Italian and Mexican versions. So I ask you Chowhounds...what is your favorite fillers and recipes for lasagna??
