Canned pasta is pretty nasty but I remember being broke as fuck working 3 minimum wage jobs barely able to afford rent with very little time or energy and absolutely relishing when I could get home, smoke a bowl, knock a can of beefaroni in a pot with some canned chilis in adobo and sit for 45 goddamn minutes and watch Star Trek.
I think, per dollar, its cheaper to make from scratch, but that's a lotta time and it's not all that much cheaper to use a can.
Is it the death of Italian cuisine? Eh, maybe, but Italian cuisine is mid anyway someone should teach them about these crazy things called spices.
