Tuna Mousse is Italy’s answer to ‘tuna salad.’ It is often found in bars during the aperativo, coffee shops and even bakeries and convenient stores. The tuna mousse is typically served as a sandwich filling or inside rolled-up roasted red peppers.
Purée the drained tuna, mayonnaise, pepper, salt, vinegar, capers (or caper berries) and onion to a smooth paste. Drizzle olive oil and blend until smooth.
