Place all ingredients, except tuna, in a bowl and beat until well combined. Mix in the tuna. Transfer to a decorative serving dish. Cover and refrigerate until ready to serve. Spread can be made several hours before needed.
Recipe Options: For a richer taste, use full fat mayonnaise. To make appetizer bites with the tuna spread, spread some on toasted slices of baguette. Garnish the top of each bite with a slice of cherry tomato, slice of black olive, and small basil or oregano sprig. Arrange the tuna bites on a platter and enjoy.
