**makes 2 pies!
1½ lbs. ground beef
1 small onion, diced (more or less to your taste)
¾ c. milk
¾ c. mayonnaise
1½ tbsp. cornstarch
2 to 2¼ c. grated cheddar cheese
salt and pepper to taste
2 frozen pie crusts
Pre-heat oven to 350°. Brown ground beef with onions, pour off fat. In a large bowl, mix beef, milk, mayo, eggs, cornstarch, and cheese. Add salt and pepper. Slit bottom of piecrusts, pour meat mixture equally into each. Bake for approximately 1 hour, covering edge of crust after 15 minutes. Uncooked pie can be frozen. To cook frozen pie, either thaw in refrigerator, or preheat oven to 450°. Cover crust edges, bake frozen pie for about 15 minutes before changing temperature to 350°. Continue baking for about 1½ hours.
I use lean ground beef, skim milk, low fat mayo, and the roll-out refrigerated piecrusts.
