Tuna "Superfood" Salad

I call this a "superfood" sandwich because it's packed with tuna AND salmon, which together are a powerhouse of protein, omega-3 fats, and selenium. The combination of the fish along with capers, onions, and crunchy celery is a tasty one. Spoon it between slices of bread for a sandwich, or serve along with crackers, cut up vegetables, or pretzel thins for a satisfying snack.
