Instructions:

Preheat to 375°F. Lightly grease cookie sheets. In medium mixing bowl sift together the flour, baking powder, baking soda, salt, cinnamon and ginger; set aside. In large mixing bowl cream the butter.  Add both sugars and beat well.  Beat in the egg.  Add the sifted dry ingredients.  With a large wooden spoon stir in the rolled oats, prunes, nuts and CHUNKS.  Roll a generous tablespoon of dough between your hands for each cookie and place 2 inches apart on prepared baking sheets.  With a fork moistened with water, flatten cookies by pressing first in one direction, and then another; they should flatten to about 1/2 inch. Bake 12 to 15 minutes. Transfer cookies to wire racks to cool. 

Variation: Figs or dates can be substituted for the prunes.
