Can cook using a microwave?

What does "Cannot cook a simple meal using a conventional cooker but can do so using a microwave" Legally mean? The PIP assessment guide part 2 says “A claimant can only satisfy this descriptor if they can prepare a meal unaided”. However, this is guidance for health professionals carrying out assessments and not law. I’m preparing for a Tribunal but having trouble picking the right descriptor for Preparing Food. The claimant can use a microwave to cook if all the preparation is done by somebody else. Which descriptor does this meet?

Thanks

Hi,
in the eye of an assessor if you can use a simplistic microwave, then you can knock up a mega gourmet meal fit for a dinner party of 12, of which only Gordon Ramsey would envy, and could not achieve lol.

Regards.
