Preheat oven to 400F. Score a ½-inch border around the edges of pastry, prick all over with a fork. Bake for 10 minutes, pressing down with the back of a spoon if the pastry puffs up.

Arrange apricot slices on pastry, leaving the border around the edges. Sprinkle with blueberries, cook in the oven for another 30 minutes. Remove from oven.

In a small bowl, whisk honey with water. Brush over fruit, sprinkle with sugar and top with slices of cheese. Slice into six even pieces.
