About Caramelized Onion and Pepper Egg Sandwiches


What sets this sandwich apart from the fray is the rich flavor of the caramelized vegetables. The key to the caramelizing is keeping the heat at medium. It’s tempting to turn it up, but slow cooking is what builds the flavor. Adding the garlic in and only sauteing it for a minute keeps it from getting bitter.

I made this a one-pan recipe because who wants to start the day with a bunch of pans to wash. It’s nice on a ciabatta bun, but sourdough bread is always a great choice as well. I usually serve the sandwiches with a side of Sambal, my Potato Waffle Latkes with Green Onions, and a cup of good strong coffee!
