In a medium-sized bowl, combine the Greek yogurt, olive oil, lemon juice, lemon zest, and minced garlic.
Stir in the dried oregano (or your choice of fresh herbs) and mix well.
Season the dip with salt and pepper to taste, and adjust the flavor with more lemon juice or garlic if desired.
Refrigerate the dip for at least 30 minutes before serving to allow the flavors to meld together.
Serve with a variety of fresh, cut-up vegetables like carrots, cucumber, bell peppers, celery, and cherry tomatoes.
Optional: Garnish with fresh chopped parsley before serving for an extra pop of color.
