To prepare the pesto, place the parsley, olives, almonds, olive oil, lemon zest, garlic, chili pepper, and salt in a food processor work bowl. Process until a chunky paste forms, 15 –20 seconds.
Meanwhile, cook the whole wheat pasta in a pot of salted boiling water according to package directions. Drain and transfer to a serving bowl, then add the NATURALE TUNA (in oil or water).
Pour the sauce over the pasta and toss together. Serve warm or at room temperature.
