Warm 2 tablespoons of the canola oil in a small saucepan over medium heat. Add the ginger, shallot and garlic and sauté for 2 to 3 minutes or until ingredients turn golden brown. Add the coconut milk, lemon juice, brown sugar, piment d’Espelette and 1 cup of the shelled pistachios. Bring liquid to a boil, reduce heat and simmer for 15 minutes; set aside. 

Generously season chicken breasts with salt and pepper to taste. Roll up all 8 halves of chicken and fix each with a toothpick. Warm remaining 2 tablespoons canola oil in a large sauté pan over medium-high heat, add the chicken rollups and brown them for 1-2 minutes on both sides.  

Transfer ingredients from simmered pistachio sauce to a blender and puree until ingredients are smooth. Pour the pistachio sauce and chicken stock into the pan with the browned chicken. Bring to a boil, reduce heat to low and simmer for about 12 to 15 minutes or until chicken is cooked through. Season with salt and pepper to taste. 

To Plate
Slice each chicken rollup in half diagonally.

Garnish with cilantro and the remaining 1/4 cup chopped pistachios.
