Season the chicken breast with sea salt and black pepper on both sides.
Heat a non-stick skillet over medium heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
While the chicken cooks, whisk together the creamy peanut butter, tamari, rice vinegar, sesame oil, grated ginger, minced garlic, and sriracha in a small bowl until smooth.
Steam the broccoli florets for 3 minutes until they are bright green and tender-crisp, then set aside.
In a large mixing bowl, combine the broccoli slaw, diced red bell pepper, and steamed broccoli florets.
Slice the cooked chicken into thin strips and add it to the bowl with the vegetables.
Pour the peanut dressing over the salad and toss thoroughly to ensure every ingredient is well coated.
Garnish with sliced green onions and serve immediately.
