My family loves this one, I got this off the Atkins board on ivillage.

ing:
1/2 lb ground beef
1/2 cup chopped onion
3 whole eggs
1/2 cup mayo
1/2 cup heavy cream
1 1/2 cups cheddar cheese
salt/pepper to taste
and any other spices you like
I even have adden some spinach

Dir:
brown beef and onion in skillet, Drain any fat or liquid from pan. Whisk together eggs,mayo, cream and spices. Mix cheese into egg mixture,then add to beef and onion. Pour all into a 8" greased pie pan. Bake at 350 for 45 min or till set. Remove and let sit 10min before serving.

This reheats really well.I even like turkey meat in it.

I hope you all enjoy.Lynn
