Preheat oven to 350. Line a baking sheet with foil and spray with a little cooking spray. In a medium bowl, combine the nuts. Drizzle with the olive oil---just enough to lightly coat the nuts. Do the same with the salt. Mix well. Layer onto the baking sheet.
Bake for 15 minutes, turning once halfway through. Since most ovens tend to run different, check often---don't let the nuts burn.
Let cool for just a minute or two and combine the nuts and papaya in a bowl.
Once the mix has cooled completely, stir in the chocolate chips. Store in an airtight container. Enjoy!
