Heat a medium skillet over medium-low heat. Spread 1/2 Tbsp of butter on each slice of bread. Once the pan is hot, add two slices of bread, butter side down, to the pan. Spread 1 1/2 Tbsps of Nutella on each slice of bread in the pan. Top with brie, evenly distributing between the two slices. Top with slices of pear and sliced dried figs. Top each slice with the remaining bread, unbuttered side down.
