I'm glad you liked them, goatlady. I haven't tried but you're right - any fruit filling would work - maybe even a nice thick jam. Here is the filling from my fig bars - that might be good:
1 cup tightly packed figs
Boiling water
1/4 cup orange or apple juice
To prepare filling, place figs in a small heat-proof bowl. Pour just enough boiling water over figs to cover them. Let figs sit 30 minutes. Drain water, and grind figs in food processor. While processor is running, add juice through top and puree until smooth.
