Heat a skillet over medium heat and add butter or oil. Once hot, add ground chicken, breaking it apart with a spatula. Cook for 5 to 7 minutes, stirring occasionally, until browned and no longer pink.

While the chicken cooks, mix lime juice, fish sauce, chili flakes, and roasted rice powder in a bowl. Stir until combined.

Once the chicken is fully cooked, transfer it to the bowl with the seasoning mixture. Gently fold in sliced shallots, mint, and cilantro until well-coated.

Separate the lettuce leaves and arrange on a serving plate.

Scoop a generous portion of the chicken mixture into each lettuce leaf.

Garnish wraps with additional herbs, minced chili, and extra rice powder if desired.
