Azizi,
   What you described having at a Pow Pow is probably what is usually called "Fry Bread." It is usually served with powdered sugar sprinkled on tip, & sometimes they might put cinnamon on it. I think that many indigenous peoples have such as that.
In the old days when the tribes were in the deep South, there was lots sweet fruit, such as peaches, which they sometimes used to make a syrup or Jam-like stuff to pour or put on the bread. (It's not all that different from the Peach cobbler that my Irish American Granny made when you think about it.) This would have been seasonal, of course, as the diet changed with the tribes moving to their favorite seasonal living spots. I have seen the old, diabetic men of the tribe (diabetes is quite common in most tribes) sitting there at gatherings eating the bread with peaches & pouring the peach syrup all over it & shoveling it in with big spoons.
