Cook the pasta in boiling salted water for twelve to 15 minutes, rinse with cold water and toss in two tablespoons of oil. Drain the olives and cut them into wedges from the stone. Wash, clean and slice the tomatoes.
Cut the sheep's cheese into cubes. Wash the parsley, dab dry and, except for something to garnish, remove the leaves. Cut turkey breast into strips. Mix the salad ingredients in a bowl. Mix pesto, vinegar and remaining oil.
Season with salt and pepper and mix into the salad. Let the salad stand for 20 minutes and serve garnished with the remaining parsley.
