Chop pitted plums by hand or in a food processor. To chop plums in the food processor place 5-7 plums at a time in the container of the food processor and pulse until plums are finely chopped.
In a large bowl combine granola and nuts. Add plums and mix thoroughly, using a spatula or knife to break up the plums. When plums are coated with the granola, add your choice of two or more of the ingredients listed above. Mix thoroughly. Store in a tightly sealed container.
Makes about 3 cups.
