Peel and cut the bananas and onions into small pieces; chop the dates into small pieces. Combine the bananas, onions and dates with the remaining ingredients, mixing well. Turn mixture into a stone casserole or crock and cook this mixture, uncovered, in a 325F. oven until it is a rich brown in color, about 1 hour. Ladle into hot sterilized jars and seal immediately.
This may be used with meats or with sour cream in crepes.
