This was really delicious and a nice change of pace from the typical egg sandwich. There were a lot of onions, and I had plenty leftover. They gave the sandwich a nice flavor with a hint of heat. I made toast in the toaster, buttered it and kept it warm in a low oven while I made the eggs. The arugula was a nice touch, and I just happened to have some fresh from the farm. Thanks for sharing this great recipe!
