(UPDATED AGAIN 2/4/12---see below *)
1/2 cup whole grain cereal or cornflakes
Place cereal flakes into a large measuring cup and add the milk. Let stand until all milk is absorbed, stirring occasionally (mixture should be mushy but not runny), about 30 minutes.
Preheat oven to 350 degrees F. Line a baking sheet with foil (preferably "Release").
In a mixing bowl, combine remaining ingrerdients except the olive oil, and add the reserved cereal mixture. Mix well with your hands. If time permits chill the mixture for about 1 hour to allow flavors to blend.
Turn mixture out onto prepared baking sheet and shape into round pattie about 2 inches thick and drizzle olive oil over the top and rub it into the meat.
Bake 45 minutes or until browned and cooked through and reaches 160 degrees F. on an instant read thermometer. Cover with foil and let sit about 10 minutes before serving.
* UPDATES: I changed my Mom;'s cornflakes to Total, Special K or bran flakes cereal; extra lean 93/7 ground beef replaced the old fatty 80/20 hamburger; Worcestershire sauce added for flavor; Her application of Crisco shortening to both surfaces of the pattie changed to just a little drizzle of olive oil on the top.
