Shepherd's pie

I call this cottage pie, as it is made with beef, but most everyone I know refers to it as Shepherd's pie.

1 lb ground beef

1 onion chopped

1 can peas

2 carrots, diced

1 pkg gravy mix 

4 cups mashed potatoes  (used the Instant potatoes)

1 cup shredded cheese

Preheat oven to 350

Cook the beef in a skillet until browned, add onion and carrot and cook until onions translucent.  Stir in peas. (My skillet is huge, so I can mix it all in that, but if your is not, transfer everything into a bowl that will hold all) Mix gravy with one cup of water.  Stir in to meat/vegetable mixture.  

Grease a 9x13 pan.  Pour meat/vegetable mixture into pan.  Top with mashed potatoes and then sprinkle with cheese.  Bake uncovered for 30 minutes.
