On Sims 3 I did it with a Sim who maxed out, or almost maxed out their cooking skill. I just used the normal fridge ingredients (using a fridge I got after an opportunity or something at work) I was at the top promotion at work though. My person had the Natural Cook trait, and one of the best stoves/counter/appliances to use too. I never grew my crops, or bothered maxing or really raising those skills at all. Every meal I had prepared no matter what was perfect.
