This was good. Made it exactly as the recipe (gorgonzola). Took lots of time and I especially liked the crunch/texture of the walnuts on top. Probably won't make again though.

This unusual lasagna with portobello mushrooms, sweet onions, spinach and Gorgonzola cheese has a rich, complex flavor. It's also great with goat cheese instead of Gorgonzola, if you prefer.
