Combine the lemon zest and juice, extra virgin olive oil, salt, and pepper in a medium sized mixing bowl using a whisk. Toss in the green onions, parsley, and oregano to coat. Toss in the beans and mix until everything is evenly combined. Finally, break large-ish pieces of the tuna into the bowl of beans. Stir gently to combine, but try not to break the tuna up too much. It's more fun to find big pieces of albacore in the salad.
