Roast pepper over an open flame on a gas stove or under a broiler to blacken and blister. Cool covered in a bowl then peel and seed. Process/blend the roasted red pepper with garlic, nuts, sherry vinegar, EVOO, parsley, smoked paprika and cayenne or hot paprika. Add salt to taste.
This sauce is great on hot, charred bread. Leftover sauce is great on any grilled, broiled or sautéed protein, grilled mushrooms or squash.
