Place a wok or large saucepan over medium heat and add the sesame seeds. Toast until evenly browned.
Add the sesame seeds to a mortar and pestle or spice grinder, and crush until the mixture resembles fine breadcrumbs. Set aside.
Place the same wok or saucepan over high heat and add the fish sauce, water and ground chicken. Break up the chicken, and saute until cooked through, but not browned.
Add the sesame oil, lemongrass, and garlic, and mix well. Cook for another minute before turning off the heat.
Stir through the shallot, galangal and lime juice. Allow the mixture to cool for about 5 minutes before adding the scallions, mint, cilantro, and ground sesame seeds. Mix well.
Spoon the mixture evenly into the lettuce leaves and top with fresh chili, if desired
