Make the sauce: In a medium bowl whisk together the peanut butter, soy sauce, ginger, garlic, sriracha, honey, sesame oil, and almond/coconut milk until smooth. Set aside.
Cut the ends off of the sweet potatoes and then use your spiralizer to spiralize it; if you don't have a spiralizer you can use a julienne peeler to make the noodles. Set noodles aside.
Next season the chicken pieces with salt and pepper. Heat 1/2 tablespoon of sesame oil in a large skillet or saucepan over medium high heat. Once oil is hot, add chicken pieces and cook for 4-6 minutes or until no longer pink. Once cooked through, remove chicken and transfer to a bowl.
Add in the other 1/2 tablespoon of sesame oil to the skillet along with broccoli florets and red pepper strips. Stir-fry for about 5 minutes until the broccoli is a little tender, then add in sweet potato noodles and cook for 1-2 minutes longer.
Next add in peanut sauce and chicken; stirring to coat veggies. Reduce heat to medium low and cook for another few minutes until sweet potato noodles are al dente. Garnish with green onions, chopped peanuts, and cilantro, if desired.
