Tuna With Roasted Peppers and Pine Nuts
- Roast the red pepper directly over a gas flame or under a preheated broiler, turning occasionally, until charred all over. Transfer the pepper to a bowl, cover the bowl tightly with plastic wrap and let cool. When the pepper is cool enough to handle, discard the charred skin, seeds and stem. Cut the pepper into 1/2-inch pieces.
- In a large skillet, toast the pine nuts over moderate heat, shaking the skillet a few times, until the nuts are golden brown and fragrant, about 2 minutes. Transfer the pine nuts to a plate.
- Add the olive oil and diced onion to the skillet and cook over moderate heat until the onion is softened, about 5 minutes. Add the red pepper pieces and the chopped tomato and cook, stirring occasionally, until the tomato is softened, about 3 minutes. Transfer the vegetable mixture to a large serving bowl and let cool to room temperature.
- Add the tuna and toasted pine nuts to the vegetable mixture in the bowl and gently toss to combine. Season with salt and pepper and serve.
