In a large bowl, combine the pickled tea leaves, shredded cabbage, and sliced tomatoes.
In a small bowl, whisk together the minced garlic, sliced green chilies, fish sauce, lime juice, tamarind paste (if using), and sugar until well combined.
Pour the dressing over the tea leaves, cabbage, and tomatoes. Toss gently to combine.
Sprinkle the crushed peanuts, toasted sesame seeds, chopped cilantro, sliced green onions, and cooked chickpeas (if using) over the salad. Toss lightly.
Enjoy your meal!
