Cut the tomatoes into bite-sized pieces or ¼ inch thick slices.
Arrange the tomatoes on a serving platter.
To make the marinade, whisk the garlic, parsley, mint, olive oil, apple cider vinegar, salt, pepper, and red pepper flakes together in a small bowl.
Pour the marinade over the tomatoes, spreading it evenly. Allow it to marinate for 1-2 hours.
