Did you not read my earlier post about how people adapt to different situations? this would be the same where people would maybe have to prepare a certain amount of their foods earlier in the week or on the weekend according to useage.

I know I will sometimes begin steaks, fish or chicken the night before by seasoning them or letting them marinate then it only takes minutes to actually cook them. toss in a side dish such as rice, beans, salad etc. which can all be prepped in advance and warmed later if need be or stuck in the fridge until use.

Excuses abound and you can always find an excuse not to do something, but in the end the solution is sometimes easier than coming up with an excuse.
