Very good recipe if you tweak it to your taste. I added more eggs (8) and used mozzarella as I didn't have muenster. I added pepper to the polenta while it was in the double boiler. I feel like I could have added garlic to the onions and it would have been really great.
I also had fresh oregano on hand so I chopped some up and put on top. Added a little depth to the flavors.
Overall, great recipe and I'd make it again
