Do you broil them on the front porch in the grill? I had suggested pan frying, which was vetoed. The fried onions and mushrooms sound delicious.
I think I was in NH once, many years ago, maybe early 90s? We went on a bus trip from MA with a company group, to a restaurant/event place up on a hillside. They served up a nice feast of whole lobsters. YUM
Fry the steaks in a mixture of butter and olive oil to desired doness Serve Onion mixture over the steaks with a salad and a side.
