Take 1 pound seedless green grapes and 1 pound seedless red grapes in a colander. Then, wash all grapes by putting them under running water. Do not forget to remove the stems of the grapes while washing, after which get a large bowl and put all of them into it.
Get another bowl and stir together 1 (8 ounce) softened package cream cheese along with 1 (7 ounce) jar marshmallow crème until their mixture becomes creamy and smooth. Now pour this mixture of marshmallow crème and softened cheese over the grapes that you have just washed.
Then, with the help of a large serving spoon or rubber spatula, blend the grapes in this creamy mixture well until they get coated completely, after which fold 1 (6 ounce) package slivered almonds with these ingredients.
You can serve this salad right away or cover it and put it in the refrigerator for at least one hour so its ingredients can sit together and combine to form a flavor.
