Slice the baguette in half and place under a broiler or toaster oven until lightly browned and toasted. I'm not going to tell you how to do this. I'm counting on YOU to know how to make toast. Please know how to make toast.

In a medium bowl, whisk the lemon juice, olive oil, pepper and salt. Toss in the arugula to lightly coat.

Assemble the sandwich like this: baguette half, halved blackberries cut-side down on the bread, arugula salad, brie slices, honey drizzled on top, then everything topped with the other half of the baguette.
