Prepare the Peppers: Preheat your oven to 450°F (232°C). Wash and dry the bell peppers, then place them on a baking sheet lined with parchment paper.
Roast the Peppers: Roast the peppers in the preheated oven for about 25 minutes, or until the skins are charred and blistered, turning them halfway through the cooking time.
Cool and Peel: Remove the peppers from the oven and cover them with aluminum foil or place them in a paper bag for 10 minutes. This will allow them to steam and make peeling easier. Once cooled, peel off the skins and remove the stems and seeds.
Slice the Peppers: Cut the peeled peppers into thin strips and transfer them to a serving dish.
Prepare the Dressing: In a small bowl, whisk together the extra-virgin olive oil, red wine vinegar, minced garlic, salt, and black pepper to create the dressing.
Combine the Salad: Pour the dressing over the sliced peppers and gently toss to coat. Scatter the anchovy fillets, capers, and chopped parsley over the top.
Marinate: Let the salad sit at room temperature for about 15 minutes to allow the flavors to meld.
Serve: Taste and adjust the seasoning if necessary before serving. Enjoy this Ibizan Roasted Pepper and Anchovy Salad as a vibrant starter or a side dish.
