Preheat oven to 400˚F. Place flatbread onto a parchment-lined baking sheet.
Brush the top with a thin coating of olive oil. Bake for 5 minutes to crisp the crust.
Remove flatbread from the oven and maintain oven temperature. Dollop the brie around on the flatbread and spread as evenly as you can. It doesn’t have to be perfect.
Spread the shallots over the brie. Sprinkle with chopped rosemary. Drizzle with 1 tablespoon of honey.
Arrange pear slices as desired. Top with prosciutto and chopped walnuts. Drizzle with remaining honey. Season with freshly ground pepper, to taste.
Bake flatbreads 10-12 minutes until pears soften, cheese melts, and crust edges are golden brown. Let cool slightly.
Garnish with fresh rosemary sprigs and additional honey, as desired. Serve immediately.
