How to Make It
Preheat the oven to 350°. Spread the pecans in a pie plate and toast for 10 minutes, until golden and fragrant. Let cool, then coarsely chop.
In a medium bowl, mash the goat cheese with the cream cheese and confectioners' sugar. Fold in the chopped pecans.
Melt 4 tablespoons of the butter in a large skillet. Add the apples and cook over moderately high heat, stirring occasionally, until golden, about 5 minutes. Add the granulated sugar and cook, stirring occasionally, until the apples are caramelized and tender, about 5 minutes longer. Stir in the water and transfer the apples to a plate.
Preheat the broiler and position a rack 8 inches from the heat. Arrange the bread on a baking sheet and brush both sides with the remaining 2 tablespoons of butter. Broil the bread, turning once, until golden and toasted, about 4 minutes.
Spread the goat cheese mixture on the toast and spoon the apples on top. Sprinkle very lightly with coarse salt. Cut each toast in half diagonally and serve right away.
