1 red onion, sliced
 1/4 c water
 1 T chili powder
 2 c cooked green beans
 1 15oz. can black beans, drained & rinsed
 1 15oz. can red kidney beans, drained & rinsed
 1 15oz. can white beans, drained & rinsed
 1 1/2 c frozen corn kernals, thawed
 2 T chopped cilantro or parsley
 
 Place the onion in a saucepan with the water. Cook gently until the onion is
 soft and separated into rings, 4 to 5 min.  Add the chili powder and stir
 until well mixed.  Remove from heat.
 Combine all of the ingredients in a large bowl and toss to mix well.  Cover
 and chill for 1 to 2 hours to allow flavors to blend.
