This Cheeseburger Quiche is definitely not diet friendly but it's so good!
Preheat the oven to 350°F.
In a skillet, brown the ground beef and the onion; drain and set aside.
In a bowl, beat the eggs, then whisk in the mayo, milk, flour, oregano, salt, and pepper.
Stir in beef mixture and 1 cup cheese. Pour mixture into pie shell.
Bake for 40-45 minutes until eggs are firm. Remove from oven and sprinkle with remaining cheese. Allow to stand for 5 minutes before cutting.
