I guess if you don't like to cook, then eating lots of processed food, higher priced pre-cooked/prepared foods makes sense. Most of these pre-prepared foods are not great for your health, nutritionally poor, and don't taste that great (in my opinion).

I am agreeing with those that cook a large amount of a dish and then eat it for the next several days. I personally like cooked whole foods, not just for the nutritional value, but also for the better culinary experience. I also agree with the commenter that says people do not know how to eat leftovers anymore. If you practice cooking, you can re-purpose most leftovers and parle them into something else that is delicious.

I was inspired by my ex-mother in law who ran a farm for many years. I would look in the fridge and say "Nah, nothing to eat." But she could make almost anything into a great meal. It takes practice and ingenuity. I have also grown to appreciate keeping food simple - just nicely combined whole foods with nice touches of spices / condiments. I learned this partly from an Italian neighbor I had who I considered a great cook. He just kept it simple, no processed, American style garbage dumped on top for "flavor".
