First, boil the eggs in water until hard-boiled. After the eggs are hard-boiled, cool in cold water.

Peel carefully, and cut the eggs in half lengthwise. Carefully remove the yolks.

Place the cooked yolks in a mixing bowl and mash with a fork until crumbled into small pieces. Set aside the boiled egg whites for later.

Drain the oil from the canned tuna and put the fish into another mixing bowl. Separate the tuna with a fork and add the tomato sauce. Stir to combine with the tuna.

Add half of the egg yolks to the bowl and mix to a paste. (To keep the mixture moist, you may need to add more tomato sauce.) Add salt and pepper to taste. Spoon this tuna mixture into the halved egg whites.

Place a small amount of mayonnaise on top of each egg. Use some of the rest of the crumbled egg yolks to decorate your deviled eggs by sprinkling over the egg halves. Then sprinkle sweet Spanish paprika over the egg halves for decoration.

Optionally, you can garnish your tuna deviled eggs with chives and cherry tomatoes. Simply slice the cherry tomatoes into quarters, and place a piece on top of each deviled egg. Sprinkle chives on top of the serving dish.

Chill the deviled eggs and keep them refrigerated until you are ready to serve them.
