Begin by shredding your leftover rotisserie chicken into bite-sized pieces using two forks or your hands.

In a medium bowl, combine soy sauce, brown sugar, minced garlic, grated ginger, and sesame oil. Whisk until smooth.

Place a large skillet over medium heat and pour in a splash of sesame oil. Heat for about 1-2 minutes until shimmering.

Add the shredded chicken and stir occasionally for around 5-7 minutes, until warmed through and just starting to crisp.

Pour the sauce over the chicken mixture in the skillet. Stir thoroughly to coat the pieces evenly.

Taste the mixture, adjusting with more brown sugar or Sriracha as per preference.

Transfer the mixture to plates or bowls and garnish with freshly sliced green onions.
