01 - Shave the green and red cabbage along with the carrots as thinly as possible using a mandoline, vegetable peeler, or sharp knife. Place the shaved vegetables in a large mixing bowl. Add the thinly sliced scallions and fresh cilantro leaves.
02 - Toast the shelled pistachios in a dry skillet over medium heat for 3 to 4 minutes until they become fragrant. Remove from heat and let cool before roughly chopping them.
03 - In a small bowl, whisk together the tahini, rice vinegar, soy sauce, lemon juice, maple syrup, sesame oil, and minced garlic. Gradually add the water while whisking continuously until the dressing reaches a creamy, pourable consistency.
04 - Pour the sesame dressing over the shaved vegetable mixture in the large bowl. Toss thoroughly to ensure all ingredients are evenly coated with the dressing.
05 - Add the toasted, chopped pistachios to the bowl. Toss the salad lightly to distribute the nuts throughout the mixture.
06 - Transfer the salad to serving bowls. Sprinkle with sesame seeds and additional pistachios if desired. Serve immediately to retain maximum crunch, or chill for 10 to 15 minutes to allow the flavors to meld.
