Preheat oven to 350 F. Cut Brie in half horizontally. Place one half, rind side down, in shallow baking dish or pie plate. Sprinkle ½ cup cheese and ½ cup muffuletta salad over Brie. Layer 1 tablespoon parsley, salami, and lemon peel over muffuletta salad. Sprinkle with remaining cheese. Place remaining Brie half, cut side down, on top. Bake until cheese begins to melt (18-20 minutes). Spread remaining muffuletta salad over top of Brie; sprinkle with remaining parsley. Serve with baguette slices.
