Cook the Noodles: Begin by cooking the noodles according to package instructions until they're perfectly al dente. Drain and set aside.

Prepare the Chicken: Cook the chicken breast over medium-high heat until fully cooked through, about 6-8 minutes. Slice into bite-sized pieces.

Mix the Base Sauce: In a bowl, mix together the low sodium tamari, honey, chili paste, toasted sesame oil, diced green onion, and minced garlic. Set aside.

Whisk the Sauce Ingredients: In another bowl, whisk together the remaining sauce ingredients: low sodium tamari, peanut butter, rice vinegar, chili paste, brown sugar, ground ginger, toasted sesame oil, red pepper flakes, water, and cornstarch.

Heat the Sauce: Pour the prepared sauce into a pan over medium heat. Stir and let it simmer until the mixture thickens slightly, approximately 3-5 minutes.

Combine Everything: In a serving dish, combine the cooked noodles, sliced chicken, and thickened sauce. Toss until nicely coated.

Garnish Your Dish: Sprinkle crushed peanuts and diced green onion on top for extra crunch and freshness.
