Yeah its the same with the ready meals,
The instructions say make sure you get all the plastic film off the tray before it goes in micro or oven.
Then MAKE it so the piggin plastic film comes off..... but moooooooooooo
You pull the film and it tears or leaves a strip around the edge of the dish....you then get a knife and try and scrape it off and still nooooooooooo
Soooo it goes in the oven and hey presto.......it melts to your piggin food.
