Combine the beans with the extra virgin olive oil, salt, pepper, and crushed red pepper and toss to combine. Allow to marinate for 20-30 minutes as you prepare the rest of the meal.
Hard-Boil the Eggs:
Bring a pot of water to a boil and lower the eggs into the water. Boil for 10 minutes (or desired time to boil). Remove and rinse with cold water. Peel and slice the eggs into rounds and season with salt and pepper.
Prepare the Tuna Salad:
Remove the tuna from the can and discard any liquid. Flake into bite-sized pieces.
In a bowl, whisk together the distilled white vinegar and sugar until the sugar is dissolved. Add the mayonnaise and whisk until smooth. Season with salt, pepper, paprika, and mustard. Add the capers and tuna and mix gently to combine.
Fold in the celery and Vidalia onion and season again to your preferences.
To Serve:
Pile the beans on top of the crusty bread and spoon the tuna salad on top. Arrange a few rounds of hard-boiled eggs on top and garnish with the parsley. Drizzle a bit of the remaining extra virgin olive oil from the beans on top of each dish. Sprinkle with parsley, if desired. Enjoy!
