Preparation / Directions:
For the dressing, mix garlic, palm or brown sugar, fish sauce, lime juice, chiles, and lime leaves in a bowl. Roughly chop shrimp and peanuts by hand or in a food processor and add to garlic mixture. (The dressing can be made in advance and stored up to 3 days in the refrigerator.)
Blanch beans in a large pot of boiling, salted water until barely tender, about 1 minute. Immediately refresh in a bowl of iced water. Tie each bean in a series of knots, 1-inch apart. Then cut between knots, so each piece has a knot in its center. Combine beans with tomatoes and zucchini in a large bowl and toss with dressing.
