In the bowl of a food processor, add the olives, capers, tomatoes, garlic, oregano, parsley, basil, lemon juice, olive oil, and black pepper.
For a relish, pulse a few times, then scrape down the bowl. Pulse a few more times, and the relish will be ready.
For a chunky spread (pictured here), pulse up to 15-17 times, stopping to scrape down the bowl a few times.
For a spreadable tapenade, process until a paste is formed, stopping to scrape down the bowl a few times.
Garnish with parsley leaves and olive oil for drizzling. Store in a covered container in the refrigerator for up two weeks.
