I thought I'd share what happens when you inadvertently grill a Marks and Spencer ready meal that should be warmed in the oven. This was originally twice the size and the black stuff is where the plastic tray was before it shrank!!
I have to confess that Gordon Ramsey I am not! I can't even warm up convenience food.... oh dear! In my defense the buttons on the oven/grill aren't clear and it's not an appliance I have much to do with!
