Ok so a few weeks ago (I don't remember exactly how many) I made quinoa. The leftover uncooked quinoa was put in a container and it's been in there ever since. I opened it and some of it looks like it turned pink? Or maybe I did something to it and it turned that way lol. It looks like the little tail-like things have come out already so I guess I should throw it away?

I know nothing about quinoa and the internet is not that helpful. Help me.

I also have lentils that I need to cook and I don't know how to cook that either...or what to put in it...
