Tuna Salad with Zucchini & Walnuts Recipe

I wasn't sure whether or not to share the recipe for this tuna salad with you, because it's the simplest thing ever, but I've been so obsessed with it recently it would be a crime not to. So, these are the ingredients I put in: romaine lettuce, plum tomatoes, corn, tuna, walnuts and sauted zucchini. I season everything with sunflower oil, balsamic vinegar and salt, but sometimes, if I'm feeling naughty, I also add in a spoon of mayo and sprinkle a little bit of cheese on top. That's it! I told you it's easy... But so, so good! Let me know if you try it.
