Preheat oven to 350. Line a baking sheet with parchment paper. Lay pecans evenly on the baking sheet and bake for 4 minutes, shake the pan to redistribute the pecans so they don't burn and bake for another 3 minutes. Remove from oven.
While the pecans are baking, warm caramel sauce in a microwave safe bowl for 30 seconds (may need to microwave for another 30 seconds if the caramel sauce has been in the fridge.) then add the brown sugar, cayenne, and salt. Stir until everything is combine (it will be very thick). Now add the warm pecans and fold the caramel mixture over the pecans, stir until all pecans are covered.
Spread the pecans onto the parchment paper and bake for another 5 minutes. Remove from oven and let sit for 5 minutes until the coated pecans cool, then break up the pecans if there are any chunks (there were lots of yummy chunks that I broke up) then enjoy!
