In a large 12-inch nonstick skillet set over medium-high heat add 2 teaspoons coconut oil.
Once the oil is hot add in the chicken and cook until lightly browned and fully cooked, about 8 minutes.
Remove the chicken from the pan and place the pan back on the heat.
Add in the remaining 1 teaspoon of coconut oil and once the oil is hot add in the garlic and ginger. Cook for about 30 seconds or just until fragrant.
Add in the chicken stock, chilies, soy sauce, brown sugar, rice wine vinegar, and hoisin sauce. Cook for about 5 minutes to help combine the flavors.
In a small bowl whisk together cornstarch and cold water.
Add the cornstarch mixture to the skillet on the stovetop. Stir to combine.
Add the chicken back to the pan and continue cooking just until the mixture is thick and coats the chicken.
Sprinkle green onions on the top and serve over rice with a side of vegetables if desired.
