What goes well with tenderloin steak and baked potatoes? You guessed it! Onions and portabella mushrooms of course. Look at that simmer. Yummy! One of the campers seen me put in the onions on and she offered to contribute her mushrooms. I couldn't turn her down. Bless her. It was awesome to be among such generous people. Things always have a way to work out. And this one was simply to die for. The icing on the beef. Great people and good food! Life can't get better than this!
