Prepare the brown rice noodles according to package instructions until al dente, then drain and set aside.
In a small bowl, whisk together the peanut butter, tamari, rice vinegar, honey, lime juice, and red pepper flakes until the sauce is smooth.
Heat the sesame oil in a large skillet or wok over medium-high heat.
Add the diced chicken breast and sea salt to the skillet, sautéing until the chicken is golden brown and cooked through.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until highly fragrant.
Add the shredded carrots and bean sprouts to the pan, tossing for 1-2 minutes until the vegetables are slightly softened but still crisp.
Add the cooked noodles and the peanut sauce to the skillet, tossing everything together until the noodles are well-coated and the dish is heated through.
Remove from heat and garnish with sliced green onions and fresh cilantro before serving.
