Any fast food place that has a value menu (so, most of them). A double cheeseburger at the local McDonalds can be had for around $1.30, and this is both tasty and filling (440cal), if terribly unhealthy.

Something that I think gets missed in this is time value. If you're poorer, you likely have less free time, and that cuts into things like shopping for groceries (doubly if you're one of the 23.5 million that live in a "food desert" [1]) and meal prep.

How is the cheeseburger unhealthy?

[Karunamon]

More than half your RDA saturated fat, almost half of your sodium, and a decent carb spike in the buns. 437cal (almost a quarter of your RDA there), and it's almost always paired with a soda and/or fries.
