How do you make the best shepherds pie?

There are many ingredients that go into a shepherds pie.  Using organic vegetables and meat is a great way to start.  You can use either minced beef or lamb but I prefer beef.  You will need to brown the meat and then add a shepherds pie seasoning mix.  Once mixed add the combination to a baking dish.  Next peel the potatoes and boil them for 20 minutes.  Once boiled you will need to mash the potatoes and add milk and butter if you want them to be more creamy.  Next steam carrots and peas and then add to the beef mixture.  Top the mixture with the potatoes and cook for 30 minutes at 350 degrees.  This is a great meal for a cold day!
