I used to include M&Ms and sometimes roasted sunflowers seeds, but now I usually stick to some combination of peanuts, almonds, walnuts, raisins, dried cranberries, sesame sticks and a bit of candied ginger for spice. Not all of those at once, but a generous selection.

Rarely, I'll add shelled pistachios just for the luxury of it. No cashews because my wife is allergic to them.
