Ok you've added 'fibrous' now, and to be honest of that list I've only steamed peas, but quickly realised I prefer boiling them if nothing else than because it's easier.

I tried kale in the microwave once (with a bit of water and covered in cling film (seran(?) wrap)) and it was awful.

To me at least 'stir in the microwave every minute to avoid building up hot spots' just isn't easier, I only use mine for defrosting/reheating things (I live alone so there's always multiple portions left over).
