The produce aisle has the cheapest food in the whole store. Inb4 you cite the price of some fancy imported vegetable as your excuse for eating pizza every night.
And no lol, I eat very healthy and mainly cook my own vegetarian food, had junk food last time maybe a month ago.
I can only speak from my own experience but if you want to have a healthy diet (enough protein and calories) where I'm from it costs a lot more than just buying cheap junk food. Well, the proteins cost.
