- 12 garlic cloves, smashed
- 2 tablespoons extra-virgin olive oil
- Pinch of dried crushed red pepper
- 2 medium heads of radicchio, quartered, cored, cut into 1/2-inch-wide strips

- Position 2 racks in center of oven; preheat to 450°F. Divide green beans and garlic between 2 heavy large rimmed baking sheets, spreading in single layer. Drizzle with olive oil; sprinkle with salt and crushed red pepper. Roast until green beans begin to brown, about 15 minutes. Divide radicchio and vinegar between sheets; toss. Continue roasting until vegetables are tender and browned in spots, about 10 minutes. Season to taste with salt and pepper.
