Start by heating the sesame oil in a large skillet over medium heat. Add the diced onions and cook them until they’re translucent, about 3 minutes. Then mix in the garlic and ginger, stirring for another minute until fragrant.
Add ground chicken to the skillet. Use a wooden spoon to break it up into small pieces as it cooks. Make sure it’s browned evenly and fully cooked, which will take about 5-6 minutes.
While the chicken is cooking, whisk together soy sauce, sweet chili sauce, lime juice, and maple syrup in a small bowl. This will be your flavor-packed sauce.
Pour the sauce over the cooked chicken, stirring well to coat all the pieces. Add in the chopped cashews, shredded carrots, and scallions. Reduce the heat to low, letting everything simmer for 2-3 minutes so the flavors meld together.
Place spoonfuls of the chicken mixture into washed and dried butter lettuce leaves. Sprinkle with cilantro, sesame seeds, and any leftover scallions for a beautiful garnish.
