It looks like the butcher sold you a nice piece of meat. On a good day I could eat that entire steak in one sitting. I can't tell what the weight is by the metric numbers you gave but it looks like its about a pound and a half to two pounds. It looks like you fixed it up just right it must have tasted great. When cows see me they should quake on their hoofs. I could make an entire meal of only a steak like that.
