Add the mayonnaise, lemon juice, zest, oregano, salt and ground black pepper to a small mixing bowl.
Whisk until combined, then set side. Add the tuna to a mixing bowl and break up any larger pieces with a fork.
Add in the red onion, Kalamata olives, red bell pepper and mint. Pour in the dressing. Toss to combine and set aside.
Slice each avocado in half lengthwise and fill with ¼ of the tuna mixture.
Top with the crumbled feta cheese and some more chopped mint, then serve.
If you are meal prepping these or are planning to have leftovers, generously rub the avocado flesh with fresh lemon juice before filling with the tuna mixture. This will help keep the avocado from turning brown in the fridge. I did this myself and it worked perfectly!
