Chop, prepare and open accordingly and mix everything together seasoning with salt and pepper. This is what I had on hand when I made the salad, leave out the artichokes and possibly the tomatoes if you want a more traditional version. I like volume and variety. Things I would love to try in different combinations with those listed in the recipe: basil basically any fresh herbs herbed goat cheese kalamata olives ricotta sun dried tomatoes pine nuts olive oil (if using tuna packed in water) italian dressing (instead of oil and vinegar) ranch dressing (if feeding children who only eat food with ranch (I actually don't want to try this at all))
