I was wondering how many people do once a month cooking?

I haven't actually one once a month cooking, but when I cook something like pork loin or chicken I make enough for at least 2-3 meals.

if you do OAMC, what type of recipes do you do? I may have a lead on a new job and it wont be traditional hours for me to be home at supper time with my family and they will need fast and easy.

Thank you for any and all suggestions.
