5-Ingredient Fix Contest Entry. This is a recipe that I stole from my mom. When we had roast beef and mashed potatoes, I always knew that if there was any left over, rare with 4 kids and always a lot of company, especially at dinner time, that there was a shepherd's pie in my future. One of my favs growing up and my mom made it so easy! * ! season the onions and carrots with salt pepper and a little ginger grated in, enough to enhance the flavor not overpower.
