Place almonds in a single layer on a medium baking sheet. Bake in the preheated oven 5 to 10 minutes, stirring occasionally, until lightly browned.
In a food processor, coarsely chop toasted almonds. Transfer to a medium bowl.
In a medium bowl, whip together cream cheese, Roquefort cheese and heavy cream. Gently fold the seedless red grapes and seedless green grapes into the mixture to coat.
Roll each grape in the chopped almonds. Place on wax paper and chill in the refrigerator until serving.
