Outstanding flavor! To save on costs, I used a combination of shiitake and baby bella mushrooms. The combination of mushrooms, cheeses, and polenta was toothsome!!!!! I cooled the polenta in the size that the recipe called for, but it didn't cover the entire bottom of the square baking pan. I would recommend either making more polenta, or cooling it in a larger width. What could have been a beautiful dish, wasn't as pleasing, because the slices of polenta kept trying to leap out as I served it. I love it, too, because it has such depth of flavor, yet isn't that horribly caloric. I will be keeping this recipe handy for company!
