Place the chicken breast in a small pot and cover with water; bring to a light simmer and cook for 12-15 minutes until the internal temperature reaches 165°F.
Remove the chicken from the water, let it cool slightly, and shred it into bite-sized pieces using two forks.
While the chicken cools, lightly toast the raw cashews in a dry pan over medium heat for 3-5 minutes until fragrant and golden.
In a small glass jar or bowl, whisk together the tamari, lime juice, grated fresh ginger, and sesame oil to create the dressing.
In a large mixing bowl, combine the shredded chicken, shredded carrots, sliced cucumber, and chopped cilantro.
Pour the dressing over the salad components and toss thoroughly to ensure everything is evenly coated.
Season the salad with sea salt and black pepper to enhance the flavors.
Divide the salad into serving bowls and top with the toasted cashews immediately before eating to maintain their crunch.
