Shepherd's Pie II

Shepherd's Pie II
2 lbs ground beef
1 onion, chopped
2/3 cup ketchup
4 teaspoons worcestershire sauce
1 (14 ounce) can whole kernal corn
1 (14 ounce) can creamed corn
3 cups prepared mashed potatoes (or instant)
salt & pepper to taste 
Preheat oven to 375°F. In a large fry pan, brown meat and onion until done. Add ketchup, worcestershire sauce & seasoning to cooking meat. Stir well. Pour meat mixture into a large rectangular pan. Pour whole kernal corn over the meat mixture. Spread the creamed corn next. Top casserole with mashed potatoes. Bake uncovered for 40 minutes. If you like the top abit crunchy, broil a few minutes before removing from the oven. (I like to sprinkle a cup of shredded cheese on top the last 5 minutes of cooking.)
