I love fruit and most of the time fruit is all that I crave, especially bananas!
1 cup dates
1 cup prunes
1 cup dried figs
1 cup raisins
1 cup dried shredded coconut
process all the dried fruit and form into a crust. Mash the bananas and fill the pie crust.
You could always add another fresh fruit for a filler. Persimmons or mango or papaya would be awesome.
