A friend of a friend made this dish at a party and it was so simple, tasty and beautiful. I didn't get the recipe, so I guessed on the proportions and it came out perfect. This is best served at room temperature. Enjoy!
Begin to drizzle olive oil and vinegar onto the mixture. Stir to combine. Keep adding oil and vinegar until all ingredients are moistened. Add salt and pepper to taste. Sprinkle on the basil. Refrigerate for a couple of hours. Pull out and stir. If mixture seems dry add a little more oil and/or vinegar to moisten.
