Ever since I was a kid, I've never been fond of most bean salads, but many years ago a friend made this black bean and bell pepper salad for me, and it has become one of my -- and my guests -- all-time favourite summer dishes. It's great for picnics, barbeques, or any pot-luck!
This recipe really needs to be refrigerated overnight to let the ingredients marinate and bring out all the flavours. Part of the appeal is in all the festive colours of the ingredients, so please, don't be tempted to substitute yellow onions instead of red, or to skimp on all three colours of peppers!! :)
