Beef stroganoff for one

I wanted something a little different so I made this for a quick lunch. I licked the plate it was so good!

Beef stroganoff

6 oz of thin sliced beef (I used flap meat)
1 tablespoon unsalted butter
couple slices of sweet onion
1 clove garlic crushed
1 cup beef broth ( I used half a large bullion cup and a cup of water)
2 tablespoons of sour cream

I sauteed the beef in butter then removed it from the pan, then sauteed the onion and garlic for a minute, adding the broth and sauteed beef simmering for a few minutes, then adding the sour cream, heating through.
