Let the Brie cheese sit at room temperature until softened.
In a bowl, mix the softened butter, minced chives, minced parsley, Dijon mustard, and grated garlic. Season with salt and black pepper to taste.
In a separate bowl, toss the arugula with lemon juice. Season with salt and black pepper.
Spread the herb butter mixture evenly on the bottom half of the French baguette.
