Preheat oven to 350 degrees. Line large jelly roll pan with parchment paper and set aside.
Pour nuts into large mixing bowl. Heat olive oil in small pan until just warm. Add 3 tablespoons rosemary and stir for one minute, or until oil is fragrant. Be careful not to let oil burn. Stir in chipotle powder, cumin, cayenne. Pour over nuts and stir well. Season with salt and pepper and stir well. (I added 2 teaspoons of salt, but use what suits your tastes.)
Place nuts on prepared pan and roast for 15-20 minutes or until golden brown, stirring once.
Remove from oven and sprinkle additional salt and remaining rosemary. Cool to room temperature.
