Since a) I live alone, and b) due to fibro, etc. I don't always have the energy to cook, what I try to do is make enough of something for a couple nights' worth of leftovers (frex sweet potato curry and rice, spaghetti, occasionally a roast or a meatloaf). If I factored that in, it would be at least 5 nights a week of home-cooked, from fresh ingredients.
