Mo, yes you can, but as I don't have experience of doing so I would suggest you consult a microwave cookbook for details if none emerge here.

Bobad's blanching info above is clearly good, but one vital element is missing, namely the power of the microwave in question. They vary considerably, and IIRC those in the USA are generally more powerful than those in the UK. Times or quantities may need some adjustment if there is a large difference in oven power.
