It was sirloin as it didn't exactly find it's way into my possession legally so, as it was dirt cheap, I didn't really mind that it was inferior (as some suggest although I'm pretty sure it is a matter of taste) steak.
In case you were wondering.
Heated a cast iron grill to max temperature. Brushed at room temperature with good olive oil. Layed on the grill with no garlic, pepper or salt for 60 seconds a side.
It was yummy with fat chips, grilled tomato and fried mushrooms.
