Romesco sauce has its roots in the Spanish province of Catalonia. Although the mixture has lots of variations, most combine roasted red peppers, nuts, garlic, and crusty bread to make a thick sauce that often tops grilled fish.
1 teaspoon smoked Spanish paprika (pimenton; see Notes)
1/2 teaspoon freshly ground black pepper
3/4 cup peeled roasted red peppers (canned or fresh)
1/4 cup whole almonds or hazelnuts, toasted
1 slice crusty bread, toasted and cut into cubes
1 tablespoon sherry vinegar
2 bunches green onions, root ends trimmed
How to Make It
If using wood skewers, soak in cold water at least 30 minutes before using. In a large bowl or resealable plastic bag, combine chicken, cilantro, 3 tbsp. olive oil, lime juice, 2 tsp. garlic, salt, smoked paprika, and pepper. Toss to coat, then marinate, chilled, 25 minutes.
Meanwhile, put roasted peppers, nuts, bread, vinegar, remaining 1 tbsp. minced garlic, and 1/4 cup olive oil in food processor and whirl until puréed; sauce will be thick.
Preheat a gas or charcoal grill to medium-high (you can hold your hand 1 to 2 in. above cooking grate only 3 to 4 seconds). Thread chicken onto skewers, discarding marinade. Drizzle green onions with remaining 1 tbsp. olive oil. Lay skewers on grill (cover if using gas) and cook 4 minutes. Turn skewers over, then lay green onions on grill. Cook 4 minutes, until chicken is browned and cooked through and onions are charred in places. Serve hot, accompanied by sauce.
