Preheat oven to 325 degrees. In a medium bowl, whisk the egg whites and honey. Add walnuts, almonds, coconut, cranberries, pumpkin seeds, oats, cinnamon and salt. Mix well, then scoop by heaping spoonfuls onto a parchment-lined baking sheet. Bake for 18 to 20 minutes, until cookies are lightly browned. Allow to cool completely on the baking sheet.
