In a large bowl, mix together the granola, cereal, raisins, cherries, pecans and pistachios.
In a large saucepan, combine the brown sugar, corn syrup, peanut butter and vanilla. Heat over medium-high heat, stirring, until it comes to a boil. Pour over the granola mixture, stirring to combine.
Scoop out the dough, roll into balls with your hands and drop onto parchment-lined baking sheets. Let cool to room temperature.
