Add black olives, green olives, garlic, oregano, and capers to a food processor. Pulse until coarsely chopped.
Add 1 tbsp olive oil and pulse again until it has the texture you want, scraping down the sides when necessary. I like it pretty finely chopped, but not a paste. Add an additional 1 tbsp olive oil if desired.
Enjoy on sandwiches, turkey and chicken burgers, on crackers or crostini, or any other way you can think of!
