Heat 1 tbsp coconut oil in a wok or large skillet over medium high heat. Add chicken, garlic, coconut sugar, soy sauce, and sambal oelek. Cook 5-6 minutes or until chicken is cooked through. Transfer chicken to a plate.
Meanwhile, cook noodles according to package.
Make the sauce by combining all of the ingredients in a small bowl. Set aside.

Add sliced scallions and chicken and cook 1 minute. Pour sauce over chicken/vegetable mixture and bring to a boil. Once boiling, cook an additional 2-3 minutes, then add in cooked noodles. Toss to combine.
Remove from heat and serve with sliced scallions, roasted peanuts, and lime wedges.
