Chop everything except the pomegranate seeds as fine as you can and mix everything together in a large mixing bowl.
NOTE: If your fruit is not very sweet, you may want to add a touch of honey or maple syrup to this. Some salt will really help bring out the flavors though. Also, if you have the time, let this sit overnight prior to serving. The onion melds with the flavors of the fruit and it becomes even better.
