Add the fresh cilantro to the bowl.
Pour in the lemon or lime juice.
Season with salt and black pepper to taste.
Gently mix all the ingredients until well combined.
Let the Kachumbari sit for about 10-15 minutes to allow the flavors to meld together. You can also chill it in the refrigerator until ready to serve.
