I’ve done the meal prep two or three times now. Our experience is the same. With two people we did it under 90 minutes but I did it by myself and it took two hours. I think a lot of it has to do with juggling the 5 sheets of instructions because it makes it difficult to work ahead and get multiple things going at the same time.

BA actually just updated their iPad app though and it honestly shaved off like 30 minutes at least. It has check boxes and you can swipe through all of the steps easily.

I don’t bother splitting them into individual servings. With both my wife and I working at home I just them into four containers and then split before eating
