Step 1Bring a large pot of water to a boil.
Step 2Place the tuna and its oil in a large serving bowl. Gently break up the tuna into bite-sized chunks.
Step 3Slice the olives in half and add to the bowl. Slice the artichokes in half lengthwise and add them to the bowl with the capers, lemon juice and parsley. Set the mixture aside.
Step 4Add salt to the boiling water, then the pasta, and cook until al dente, 7 to 10 minutes. Drain. Add to the tuna mixture and toss well to combine. Season to taste with salt and pepper.
