- Preheat oven to 350 degrees. Line a large baking sheet with parchment paper.
- In a large bowl, whisk together the egg whites, cayenne pepper, coconut palm sugar and salt. Add the nuts and toss to coat evenly in the seasoned egg mixture.
- Spread the nuts out on an even layer on the parchment-lined baking sheet. Bake for 20 minutes. Add the dried pineapple or mango (or both) and the rosemary. Return the nuts to the oven and bake 5 more minutes. Remove nuts from oven and set aside to cool for at least 10 minutes before serving. (Note: Party nuts can be made up to 1 month in advance and stored in the freezer in an air tight container.)
