Gluten-Free Steak Marsala with Onion and Mushrooms

One of my favorite entrées is chicken or veal marsala. I had the craving, but no chicken or veal in the house. Oh my!  Onto another experiment I went…and here it is, steak marsala, gluten-free, of course! After making the test recipe for just my husband and I, we had a guest over and I made it again. I hope you enjoy it as much as our guest did. She had that, “That was yummy!” and said, “That was really good!” – as if she were surprised that she enjoyed it that much.

Note: If you are sensitive to trace amounts of gluten, do not consume mushrooms. They are often grown on wheat though they usually test well below 20 parts per million.
