I was reading this http://www.chow.com/stories/11811/2
And I never knew there were purple peppers!
I have an idea for a purple salad, with red onion, purple pepper and purple leaf (not sure which one).
What else purple could go in there that would taste good? Beetroot is an obvious one, but I hate the taste.
Or if anyone has any other colour schemes (rainbow?) post up your ideas!
