Shepherd's Pie in a Cast Iron

Our daughter loves to cook with cast iron. While home one weekend she made us her version of Shepherd's Pie. The twist was, that by using cast iron, she could do it all in one pan. Brown the burger (or any ground meat) on the stove top, then make your layers and pop it in the oven. Simple is very good and the layer of cheese on top - even better.

Ingredients
1 lb. ground beef or other meat (venison, turkey etc.)
1  pkg. (16 oz.) frozen mixed vegetables (or choice of leftover cooked veggies)
4 cups seasoned mashed potatoes
8 oz. (1 cup) shredded cheddar cheese
salt and pepper

Preparation
Preheat oven to 375 degrees. Brown meat in cast iron skillet. Drain. 
Place vegetables on meat (in skillet) and sprinkle with salt and pepper. 
Top with mashed potatoes, spreading to cover. 
Bake 30 minutes. Remove from oven, top with cheese, continue baking 10 minutes or until cheese melts. 
 Let rest for 5 or 10 minutes. Serves 6.
