I cook bacon and then scramble the grease into eggs and cover them with cheese. Salt and pepper to taste. If I’m having bacon and eggs, it winds up being about 6-12 eggs in a meal depending how much bacon grease I manage to get.
Another favorite for me is to take 4 quarter lb burger patties (75% lean or fattier) and cook them over medium in a fry pan. I cheese and salt them generously and then stir fry vegetables into the grease that collects in the pan. I add Parmesan cheese to absorb the grease and add creole seasoning.
