Heat a large skillet over medium-high heat. Once hot, add the ground chicken and cook until browned. Be sure to break up the meat as it is cooking so there are no big pieces. When chicken is completely cooked, drain liquid and place chicken in a bowl and set aside.
Heat 1 tablespoon oil in the same large skillet. Once heated, add the coleslaw and carrots and sauté until it cooks down and softens, ~5-7mins, stirring occasionally.
As the coleslaw mixture is cooking prepare the sauce. Add all the sauce ingredients into a small bowl and whisk until well combined.
To the skillet, add the garlic, stir, and cook for an additional minute. Add the water chestnuts and cooked ground chicken to the skillet and stir to combine.
Add the sauce to the pan and stir well, let cook for another 3-5 minutes stirring occasionally. The sauce should reduce and coat the mixture well. When ready to serve, take off heat and stir in scallions and cilantro.
