- 1/4 cup walnuts
- 2 red bell peppers (about 1 pound)
- 1 garlic clove, grated
- 1 tablespoon finely chopped fresh mint
- 1 tablespoon olive oil
- 1 teaspoon (or more) Aleppo pepper or 1/2 teaspoon hot smoked Spanish paprika
- 1/2 teaspoon (or more) fresh lemon juice
- 1/2 teaspoon pomegranate molasses or balsamic vinegar

- Heat broiler. Broil bell peppers on a broiler-proof rimmed baking sheet, turning occasionally, until softened and skins are blackened in spots, 20–25 minutes. Transfer bell peppers to a bowl, cover with plastic wrap, and let steam 15 minutes. Peel peppers, seed, and chop.
- Toss bell peppers, garlic, mint, oil, Aleppo pepper, lemon juice, pomegranate molasses, and walnuts in a small bowl; season with salt, black pepper, and more Aleppo pepper and lemon juice, if desired.
