We're assuming you're asking about beef steak, tesco have steaks of plenty of other meat varieties.. http://www.ciao.co.uk/sr/q-tesco+steak - any of these look like yours? (PS they all have labels....)
Its beef steak, there are no clues as to the cut, I thought the cooking instructions might have given me an idea, but there are frying grilling and oven cooking instructions. I dont normally eat steak but I thought i would treat myself, thats why I dont want to ruin it by making a mess of cooking it wrongly...
