Method
Wash and dry the salad leaves.
Combine the oil, vinegar, and mustard in a jar. Toss the dressing over the leaves and capsicum. Arrange the leaves on individual plates, and top with slices of mackerel, and the rest of the salad ingredients.
Season with black pepper and serve with individual sourdough grain rolls.
Note: Mackerel is a rich source of EPA, a naturally occurring food chemical known to help increase the production of prostaglandin E1, a compound known to reduce blood pressure. A study found that eating fresh mackerel twice a day for two weeks significantly reduced the blood pressure of patients suffering from mild hypertension.
