I'm talking about top ramen and you're talking about pork stew and lasagna? Way to prove you're out of touch.
Even if I take your pork stew example
Let's assume you only use a half pound of pork that you got on sale, that's at least $1.00. the potatoes are another $.50, the carrots $.50, and the celery another $.50. so the minimum cost of a batch of pork stew is $2.50. this does not include any seasonings or take into account whether or not they can afford to even keep the gas on or refrigerate the ingredients or any leftovers (since you apear to be out of touch with poverty, I'll bet you didn't even consider that cooking or refrigeration could be issues). Whereas two packs of ramen are $0.40, can cook in any hot water, and are, prior to cooking, shelf stable and require no refrigeration.
And don't get me started on you lasagna example (which you compared to takeout, a luxury that many simply cannot afford anyhow). The cheese alone will run you at least $4, noodle another $1, and a can of cheap spaghetti sauce is another $1 (even more if you make the sauce from scratch). That's a minimum of $6.00, without added meats or vegetables. Spaghetti might have been a better example, as that can be done for $2.00 ($1 for the pasta, and $1 for the can of sauce), but even that is more than double the cost of a "meal" of top ramen.
Right now. I'm about where you are. I'm currently cooking meals of potatoes, carrots, celery and turkey (whole turkeys were on sale for only $0.22 a lb, yay). I had to defrost them an cut them into meal portions and refreeze them. The fridge part of my fridge crapped out (the freezer still works), so leftovers weren't an option (I have since got a mini-fridge for until I can replace the full size one, and use that and the freezer part of the fridge). I cook most things in the rice cooker, since my gas was turned off, but we do have a microwave and hot plate.
While I am struggling, I am more than aware that I have much further I can fall, and I have existed through those weeks where it was top ramen, because $2.00 worth would get through an entire week.
