Psst! This (http://www.savoryreviews.com/2010/05/10/salmon-with-mango-salsa/) sounds pretty close to what I remember having. Though the one I had had green onions instead of red onions, and cherry tomatoes instead of red peppers (I assume they're meaning what I'd call a red bell pepper (http://en.wikipedia.org/wiki/Bell_pepper) when they say "pepper").'

It'd be fun to mess around with to suit individual tastes.
