Step 1: Choose a theme or let guests pick countries. Communicate clearly what each person should bring to avoid overlaps and ensure diversity. Plan your own board contribution in advance.

Step 2: Prepare your designated country's contribution. For Greek, assemble tzatziki by mixing yogurt, cucumber, garlic, and dill. Arrange feta, olives, and pita on a platter.

Step 3: If making Chinese, cook spring rolls and dumplings according to package directions. Arrange with dipping sauces and sliced scallions.

Step 4: For Italian, artfully arrange prosciutto, salami, cheeses, tomatoes, and basil on a board. Drizzle with balsamic glaze and serve with bread.

Step 5: On the night of the event, set up a large central table. Arrange all the different country boards/dishes, ensuring clear labels for each cuisine. Provide small plates and utensils.

Step 6: Encourage guests to mingle and sample the global array of flavors. Enjoy the culinary journey and cultural exchange!
