Preheat oven to 350 degrees F. Line a baking sheet with parchment, a silicon mat or a sheet of wax paper and set aside. In a medium bowl, add cashews and vegetable oil and toss.  

To a small saucepan, set over medium heat, combine brown sugar, water and honey. Bring to simmer for about a minute, until the sugar has dissolved. Pour the honey mixture over the cashews, sprinkle with a teaspoon of salt and toss once more. Transfer to the center of the baking sheet and spread out in one even layer. Bake for 7 minutes and remove from the oven. Add sesame seeds and toss lightly. Bake for an additional 7 minutes, until lightly toasted. Sprinkle with remaining 1/4 teaspoon of salt and a bit more sesame seeds if needed. Allow to cool until warm on the baking sheet, breaking them apart with your hands to avoid sticking.
