Whip the Garlic & Herb Dip: In a medium bowl, whisk together the Greek yogurt, mayonnaise, minced garlic, fresh lemon juice, onion powder, salt, and black pepper until completely smooth and creamy. Fold in the finely chopped fresh dill, chives, and parsley until evenly distributed. Spoon the dip into a decorative bowl and chill in the fridge for at least 15 minutes.
Prep and Wash the Vegetables: Wash all fresh produce thoroughly under cold water and pat completely dry with paper towels. Trim and slice your cucumbers, celery, bell peppers, and radishes into clean, even cuts.
Assemble the Target Display: Place the bowl of chilled dip right in the center of a large round wooden board or ceramic platter. Arrange the colorful vegetables in neat, tight rows expanding outward from the center. Garnish the top of the dip with a drizzle of extra virgin olive oil and fresh herbs.
Serve Cold: Serve immediately while the veggies are crisp and cold, alongside extra crackers or pita chips if you want!
