How to Make It
In a large, deep, nonreactive bowl or heatproof glass jar, combine the cauliflower, carrots, fennel, red bell pepper, zucchini and beans.
In a medium heatproof bowl, cover the chiles with boiling water and let stand until softened, about 10 minutes. Drain the chiles and transfer to a large saucepan. Add the cider vinegar, white wine vinegar, sugar, salt, coriander, peppercorns, ginger, bay leaf and garlic. Add 3 cups of water and bring to a boil, stirring to dissolve the sugar.
Pour the hot liquid over the vegetables and cover with a plate to keep the vegetables submerged. Let cool to room temperature, then cover with plastic wrap and refrigerate for 2 to 3 days.
Drain the vegetables and transfer to a large platter. Drizzle with olive oil, garnish with the parsley and chives and serve.
