Cowboy's Beef Pie
Source: the May, 2001 issue of Chronicle of the old West

When the cowboys were on the trail, since supplies were limited, nothing went to waste. This recipe is a great one for using up leftovers, because everything in this cowboy's beef pie can be precooked.

4 cups cubed, cooked beef
2 1/2 cups of gravy
3 cups of vegetables (you can use potatoes, carrots, string beans, peas or any other canned or fresh vegetable on hand)
1 small minced onion
1 tablespoon parsley flakes
Salt & pepper to taste
3 cups mashed potatoes
1 well beaten egg

Combine meat, gravy, vegetables, onion, parsley, salt, and pepper in Dutch oven. Heat to boiling point. Stir often.
Mix mashed potatoes and egg in a separate bowl.
Cover the meat and vegetables in the Dutch oven with the potato and egg mixture.
Bake at 425° until the top is brown (15 to 20 minutes).
