Combine feta cheese, cream cheese, Greek yogurt, lemon juice, Greek seasoning, garlic, dill, and black pepper in a food processor.

Blend until smooth.

Transfer the mixture to a bowl.

Garnish with red pepper flakes (optional).

Refrigerate the dip while you assemble the snack board.

Place pickled cauliflower, artichoke hearts, pickled okra, hummus, and Kalamata olives in separate small serving bowls.

Arrange the bowls on a large cutting board or platter.

Add the dip bowl to the arrangement.

Arrange Cheddar cheese, cherry tomatoes, red grapes, baby carrots, red bell peppers, cucumber, crackers, pita chips, salami, pepperoni, almonds, blackberries, and roasted chickpeas around the bowls on the board, ensuring not to overcrowd.

Keep extra ingredients in covered containers in the refrigerator to replenish the board as needed.
