This family-favorite meal uses ground beef and your favorite vegetables. To make it fast and simple, use pre-cooked mashed potatoes to quickly whip up this Easy Shepherd's Pie for a dinner that your entire family will love.
In a mixing bowl, combine mashed potatoes, egg, 1 teaspoon salt (optional) and 1/4 teaspoon pepper. If using pre-cooked mashed potatoes, you may want to taste potatoes before adding the egg to see how they are seasoned. If they are already salted appropriately, you can omit the salt.
