Preheat oven to 275°. Pulse almonds in a food processor until finely chopped (do not overprocess). Spread in a 15x10x1-in. pan; bake until golden brown, 6-9 minutes, stirring occasionally. Transfer to a shallow bowl; cool slightly., In another bowl, mix cream cheese, blue cheese, parsley and cream until blended. Insert a skewer into each grape. Roll grapes in cheese mixture, then in almonds; place on waxed paper-lined baking sheets. Refrigerate, covered, until serving.
