Prep time: 20 minutes. Cook time: 0 minutes. Total time: 20 minutes. Servings: 8 to 10. Use a clean food-safe rectangular serving board approximately 12 by 18 inches. Prepare 1 1/2 cups cheddar cheese cubes, 1 1/2 cups mozzarella or Monterey Jack cheese cubes, 1 cup folded beef salami or ready-to-eat turkey slices, 1 cup green grapes, 1 cup red grapes, 1 cup cherry tomatoes, 1/2 cup pitted green olives, 1/2 cup pitted black olives, 1 cup crackers, 1/2 cup mixed nuts, approximately 6 fresh rosemary sprigs, 1 star-shaped slice of cheese, and optional 2 tablespoons dried cranberries. Wash and dry all fresh produce thoroughly and drain olives. Start with a short row near the top of the board and arrange ingredients into gradually wider horizontal rows to create a triangular Christmas tree shape. Alternate red, green, golden, ivory, and dark ingredients. Tuck rosemary sprigs around the edges, add a cheese star at the top, and create a trunk with crackers or cheese cubes. Fill gaps with nuts and optional cranberries. Serve immediately or keep refrigerated until serving. Add crackers shortly before serving to prevent moisture-related softening. Choose pitted olives for convenience. Use clean rosemary as decoration and avoid serving the woody stems as food. For young children, quarter grapes lengthwise and consider serving nuts separately because whole grapes and nuts can present choking hazards. For guests with nut allergies, omit nuts or offer them in a clearly labeled separate bowl and prevent cross-contact. To prepare ahead, cube cheese, fold meat, and wash and dry fruit in advance, then refrigerate each perishable component separately. Keep assembled perishable ingredients at 40°F (4°C) or colder until serving. Do not leave perishable foods at room temperature for more than 2 hours, or 1 hour above 90°F (32°C). Replenish from chilled ingredients during long parties. Nutrition values are approximate per serving assuming 10 servings and optional dried cranberries. Exact values depend on meat type, cheeses, cracker varieties, olives, nuts, and quantities consumed.
