A few weeks ago, Hungry Bear and I went to lunch at Ella's, our favorite breakfast place in San Francisco. Usually, I order a burger or a heavy egg scramble for lunch, but this time I went with a mushroom, onion and gruyere sandwich on a buttermilk bun. The sandwich was great and I knew immediately, we were going to make this at home.

We tried to replicate the sandwich a couple of days ago. It was easy to make and only required sautéing onions and mushrooms. Our version of the sandwich included portobello mushrooms, crimini mushrooms, onions and provolone on a focaccia roll. It was supposed to be gruyere, but our Trader Joe's didn't have any... not that provolone is a second class cheese. The sandwich was simply delicious. We served the sandwich with a tomato and English cucumber salad. If we had a ripe avocado, it would have gone into the salad too.
