As long as they are the ones that look a bit like real burgers they are the free ones. They are quite nice,just dont cook them for too long as they dry up, I put in microwave for 1 min and then just brown in the fry pan for another min. great with a fry up. let me know what you thought of them.
I love these things, take out the freezer, spray of frylight on each side, whack them in the George Forman, mince about a bit, have a wee, smoke a cig, put some lettuce on a plate and then chuck the burgers on fabulous!
