2 tablespoons butter
1/3-1/2 cup heavy cream
1 tablespoon mashed potatoes
~12 fresh sage leaves
1/2 teaspoon salt
a small pile of pieces of roasted chicken
~1 cup mashed potatoes
melt butter in a large saucepan on medium-low heat. once melted, add sage leaves and fry until crispy. butter should brown a little, but not blacken (if it does heat is too high). remove sage leaves with a fork and set aside. add heavy cream, tablespoon of mashed potatoes, and salt to saucepan, and stir thoroughly with a whisk. lower heat a little and simmer until sauce reaches a somewhat thickened but still flowing consistency--this should take only a couple minutes.
heat up chicken pieces and mashed potatoes in somehow (a microwave probably), pour sauce on top, and garnish with crispy sage leaves.
