Break the uncooked ramen noodles into small bite-sized pieces. Do not cook them to keep them crunchy.
Toast the slivered almonds and sunflower seeds in a dry skillet over medium heat for 3-4 minutes, stirring frequently until golden and fragrant.
Shred the cooked chicken breast into thin strips or bite-sized pieces. Slice the green onions, thinly slice the red bell pepper, trim the snap peas, and shred the carrots.
In a small bowl, whisk together sesame oil, soy sauce, rice vinegar, honey, garlic powder, ginger powder, salt, and pepper. Adjust seasoning to taste.
In a large mixing bowl, combine broken ramen noodles, toasted almonds, sunflower seeds, shredded chicken, and chopped vegetables. Pour the dressing over and toss gently but thoroughly.
Refrigerate the salad for at least 15-20 minutes before serving to allow flavors to meld without soggy noodles. Serve chilled or at room temperature.
