I get a lot of lean ground beef in my co-op packages, so I tend to throw 1lbs of beef into a pan, cook it with two handfuls of different veggies, and call it a day.
I had leftover bacon fat in my pan from breakfast today. Browned onions, garlic, and a pound of beef in it. Added some chopped kale, some chopped parsley, and some curry powder as well as a few other spices.
Ate the whole damn thing. 1200 calories worth.
Normally if I'm in a hurry, a tablespoon of coconut fat gives me my morning calories if I know I'm gonna miss breakfast and I dont want to IF.
