Besides my bacon and avocado sandwich on toast, my favorite lunch sandwich is something that is so easy to make. It also is meat free and comes together very quickly. Portobella mushrooms are very hearty and some sweet Vidalia onions complete this sandwich.
Some crusty French bread
3 medium sized portabella mushrooms or two large
1/4 onion diced
cheese of your choice like Swiss
2 pats butter
pinch of Thyme
Melt the butter and add the mushrooms and onion. Give them a stir every few minutes until they have reduced (about 5 minutes) You can start out with a bunch of mushrooms and end up with just a little. Season with Kosher salt and the Thyme. Slather Miracle Whip on both sides of the bread. Add cheese and then the mushrooms.
note: If you add the cheese you can put it under the broiler for 3 minutes until the cheese is melted.
