If using fermented tea leaves, rinse them under cold water and drain well. If they are too salty, soak them in water for a few minutes and drain.
In a large bowl, combine the shredded cabbage, cherry tomatoes, crushed peanuts, toasted sesame seeds, fried garlic, dried shrimp (if using), and green chili peppers.
In a small bowl, whisk together the lime juice, fish sauce, soy sauce, palm sugar, and salt until the sugar is dissolved.
Add the tea leaves to the salad mixture. Pour the dressing over the salad and toss everything together until well combined.
Enjoy your meal!
