How to Make It
Roast the peppers over gas flames or under a preheated broiler, turning often, until charred all over. Transfer the peppers to a platter and let cool.
Meanwhile, bring a medium saucepan of salted water to a boil. Add the leeks and cook until just tender, about 3 minutes. Drain and pat dry with paper towels. Return the leeks to the saucepan with 1 tablespoon of the olive oil and toss to coat. Season with salt.
Discard the pepper skins, stems and seeds. Cut the peppers into 2-by- 1/3-inch strips and arrange on a large platter. Drizzle with the remaining 1/4 cup of oil and season with salt. Top with the leeks and serve.
