It is advisable to tie the package with a knot. Shake to mix everything up. Pierce the package three times at the top (I pierced it with sharp scissors).
Put the bag on a plate and put it in the microwave for 20 minutes. In my microwave oven, the power level of the mode is called “high”.
In 20 minutes, I looked into the microwave a couple of times, shook the bag of vegetables a little and checked how soft the vegetables were.
