In a saucepan combine dates, raisins, prunes and water. Bring to boil and boil 5 minutes. Stir in margarine and salt. Set aside to cool.
Add remaining ingredients to fruit; stir just until dry ingredients are moistened. Spoon into greased Mini-muffin pans. Bake in preheated 350-degree oven for 15 minutes. (If desired can bake in a greased 11 x 7 x 2-inch pan for 30 minutes.)
