Step 1

Stir all ingredients in a small bowl to blend; set dressing aside.

Step 2

Combine first 8 ingredients in a food processor. Drizzle 1 Tbsp. oil over and pulse until chicken is very finely chopped. Heat remaining 2 Tbsp. oil in a large heavy nonstick skillet over medium–high heat. Add chicken mixture and sauté, breaking up into small pieces with the back of a spoon, until chicken is starting to turn golden brown and is cooked through, about 6 minutes.

Step 3

Place 2 lettuce leaves on each plate. Top leaves with chicken mixture, dividing evenly. Garnish with cilantro and spoon reserved dressing over.
