Quick Giardiniera

Combine vinegar, water, sugar, bay leaf and 1/2 teaspoon each crushed red pepper and salt in a large saucepan. Bring to a boil.

Add cauliflower, celery, carrot and bell pepper. Reduce the heat to maintain a lively simmer and cook until the vegetables are tender-crisp, about 5 minutes. Remove from the heat and let stand for 5 minutes. Reserve 3 tablespoons of the cooking liquid, then drain.

Transfer the vegetables to a medium bowl. Stir in oil, pepper, the remaining 1/2 teaspoon each crushed red pepper and salt and the reserved cooking liquid. Refrigerate for at least 25 minutes to chill. Stir and serve with a slotted spoon.
