Place all ingredients in a very large blender or food processor. (It may be necessary to do this in 2 batches; just add 1/2 of each ingredient and then repeat.) Blend for 1 minute, or until thoroughly combined and mixture is smooth. Pour sauce into a large bowl.
Use when grilling chicken; brush lightly over the chicken during the last few minutes of grilling. This sauce is also great for dipping; set some sauce aside for passing at the table.
