In a medium mixing bowl, combine the crumbled feta cheese, chopped green olives, softened cream cheese, Greek yogurt, lemon juice, olive oil, garlic powder, black pepper, and red pepper flakes (if using).
Using a hand mixer or a fork, blend the ingredients until smooth and creamy, ensuring there are still some chunks of olives for texture.
Taste and adjust seasoning if necessary, adding more lemon juice or pepper according to your preference.
Transfer the dip to a serving bowl and cover with plastic wrap. Refrigerate for at least 30 minutes to allow the flavors to meld.
Before serving, garnish with chopped parsley. Serve with crackers, pita chips, or fresh vegetables.
Notes
For a creamier texture, add an extra tablespoon of Greek yogurt or cream cheese.
Substitute black olives or a mix of olives for a different flavor profile.
