from https://www.foodnetwork.com/

2 cups leftover mashed potatoes
a heaping 1/3 cup flour
2 tablespoons milk
1 tablespoon chopped mixed herbs

Combine all ingredients in a bowl; knead until smooth. Season with salt and pepper. Divide into 4 balls on a floured surface and flatten each into a 3-inch patty. Melt 1 1/2 tablespoons butter in a large skillet over medium-high heat; add the patties and cook until golden brown, 4 to 5 minutes per side, adding more butter to the pan as needed. Season with salt.
