Place all salad ingredients in large bowl, toss lightly and set aside. For the dressing, whisk vegetable and sesame oils, soy sauce, garlic, lemongrass, and ginger briskly in a bowl until creamy. Add broth, lemon juice, and pepper and again whisk until creamy. Drizzle dressing over salad and toss gently. Taste for salt, adjust as needed, and serve.
