Shepherd's Pie

I'm finally posting again...and it's for shepherd's pie.  My teenage self would find that comical as I loathed Shepherds Pie growing up.  I like it more now (acquired taste?), and as a mom I also like that it recycles leftover mashed potatoes and is made with things I typically keep on hand.

Ingredients:

1 lb. lean ground beef

1 onion, chopped

2 cups frozen mixed vegetables

10 oz. can cream of mushroom soup with roasted garlic

1 tsp. dried marjoram leaves

Salt and pepper to taste

3 cups refrigerated mashed potatoes

Directions:
Preheat oven to 375 degrees. In heavy skillet cook ground beef and onion until beef is brown and onion is tender, stirring to break up meat, about 10 minutes. Drain well. Stir in vegetables and soup and cook until hot, about 4 minutes, then add marjoram and salt and pepper to taste.
Place in 9 inch pie plate. Spoon mashed potatoes over hot meat mixture.

Bake at 375 degrees for 35-45 minutes until potatoes are golden brown and pie is bubbling.
