Season beef breakfast steak with salt, liquid seasoning, ground pepper and calamansi juice.
In a heavy pan, heat butter and fry the steaks on both sides until brown. Transfer steaks to a platter and set aside.
In the same pan, add fresh whole oyster mushroom. Saute for a while then stir in beef bouillon cubes and dissolve in butter.
Thicken with flour. Cook for about 1 minute then pour in milk. Let boil. Then pour the sauce over steaks.
If you want to have a sizzling steak, heat the sizzling plates on a stove until hot. Put the steak then pour the sauce over to have a sizzling effect. Garnish with parsley or scallion.
