Instructions
Open tuna cans and carefully drain out olive oil reserving 1/4 cup of it. Pour 1/4 cup of reserved olive oil into a large mixing bowl.
To the mixing bowl add lemon juice and dijon mustard. Whisk to combine.
Mix in capers, celery, red onion, and tomato gently.
Add in tuna and flake gently with a fork. Add 1/4 tsp salt to start. Stir 2 or 3 times to combine tuna with the rest of the ingredients. Taste. Season with more salt as desired.
Refrigerate until ready to serve and optionally marinate for 2 hours.
When ready to serve, gently stir the ingredients to redistribute the salad dressing ingredients that may have fallen to the bottom of the bowl.
If using, fill hollowed-out lemon halves with tuna salad and garnish with fresh parsley.
