Stir fry black bean pork

I don't know whether any of you have this kind of feeling when daylight are getting shorter as one progressing through autumn and winter. I have a fake sense of time, i.e it gives me feeling that it's really late when I got back home from work. I tend to prepare simple one dish meal, eat it quickly and settle in front of my TV just to realise I've done all that in about 30minutes.... how can that be? Super efficient? Or was it really a super simple meal? :-)
Here it goes with my stir fry black bean pork recipes......
