I am one of those guys who always skipped cooking and now my body is punishing me for it. Today i had a serious stomachache and doc advised me to stop eating quick and cheap food. I don't know whether this is a good place to post but I am a man who lives alone(I'm 21) and most cooking guides I have found online are complicated.

I need something to begin with that's quick, easy and healthy to make. Any ideas?
