I just cooked myself a cheap cut of steak and it was one of the best I have had ever.
Morisons 'beefsteak', had a nice marbling and about 3/4" thick. ?2.46
Seasoned with salt, black pepper and garlic granules and fried, after I fried the onions, for 1.5 mins per side, seasoning the second side just before I flipped it.
Served with onions and 'double cooked' chips, fried in lard.... it was awesome.
Now, I have had sirloin, t-bone, fillet and rib eye before and I can honestly say that this was as good as any of those in terms of flavour, tenderness and juicyness.
I cant be done with additional sauces, if its cooked right its served in its own sauce

So whats your prefered cut and style?
