Heat broiler to high. Slice baguette and toast for 2-3 minutes per side, watching closely to prevent burning. Set aside.
To make the whipped honey goat cheese: add cheese, yogurt, honey, and salt to a food processor. Blitz until smooth and creamy. Pour into a bowl and drizzle with additional honey, then sprinkle thyme leaves overtop. Set in the fridge until ready to serve.
To make the olive bruschetta: toss the olives and feta with olive oil, basil, dill, thyme, oregano, lemon peel, red pepper flakes, and a pinch of salt and pepper. Let marinate at room temperature while you prepare the board.
To assemble the board: place bowls of whipped goat cheese and olive bruschetta in the center of the board, then set down blue cheese. Arrange crostini around the bowls and the blue cheese. Add salami and prosciutto. Fill in the corners with fresh fig halves and grapes. Finish with hunks of dark chocolate.
