Does anyone like Shephards Pie?

I have never actually followed a recipe when making a Shepherd's pie. I normally cook up some onions, celery, and ground beef in a skillet, add some frozen corn and make a gravy with some butter, milk, and flour. Then I top it with mashed potatoes with some cheese mixed into them and bake. Oh, and I season it with salt, pepper, and sometimes a little thyme.

I love shepherds pie. I was thinking about making this tonight but with sweet potatoes instead of regular potatoes. Here is the recipes I use - quick and easy! I do modify it a bit based on what I have on hand http://www.foodnetwork.com/recipes/rachael-ray/30-minute-shepherds-pie-recipe/index.html

1 lb. ground beef 1 can peas 1 can sweet corn 1 medium onion, diced 1/3 c. sugar 8 medium potatoes 2 c. shredded sharp cheddar cheese Boil potatoes, mash and season to taste with milk and butter. Brown ground beef and onion with salt and pepper. When cooked, add peas, corn, sugar. Let simmer until heated through. In 13x9 pan place meat and vegetable mixture in bottom of pan. Cover with mashed potatoes and sprinkle cheese on top. Place in oven on BROIL until cheese is bubbly or light brown I don't have it often, but it is yummy!
