Using a small sharp knife, carefully cut into each olive to remove the pit without tearing the fruit, setting the pit aside and keeping the olives intact.
In a mixing bowl, combine softened cream cheese, chopped herbs, lemon zest, and a pinch of salt. Mix until smooth and fragrant, watching for a creamy, uniform consistency.
Using a small spoon, gently fill each olive with the herb cream cheese mixture, pressing slightly to ensure the filling stays in place and is neat on top.
Place the stuffed olives on a plate, then drizzle lightly with olive oil and sprinkle with toasted nuts for added crunch and flavor. Let them rest for about 10 minutes to allow the flavors to meld.
If desired, chill the olives in the fridge for 15-20 minutes before serving to firm up the filling and enhance the flavors.
Serve the stuffed olives at room temperature, enjoying their vibrant appearance and layered flavors as a perfect appetizer or snack.
