Filet Mignon with Balasmic & Red Wine

This is one of our favorite ways to prepare filets in the winter when grilling isn't quite so appealing.

Ingredients:

Filet mignon (how many depends if you want leftovers or not)
1 red onion, sliced
mushrooms (I usually use 1/2 package), sliced
Salt and pepper
balsamic vinegar
red wine

Put a large skillet on the stove and preheat to med-high.  Add red onion first to start to soften it-

Add steaks and surround with mushrooms -

Cook for about 5 minutes and then add balsamic and red wine to cover the steaks.  I use more balsamic than wine.

Cook to desired doneness, flipping once.  We like ours medium-rare, especially with these fresh, grassfed steaks!

Serve with brussels and rice pilaf.
