You're looking at extremes, while I'm saying that once you cannot afford meat anymore, you cannot afford vegan alternatives either. If you can't pay 2eur for a piece of pork, you can't afford a 3-pack of bell peppers either. But you can afford a 60c half-kilo pack of pasta.
If I can buy a piece of pork for 2 EUR at my German supermarket, then this is because of the meat industry in Germany being subsidized with an estimated 13 billion EUR yearly.
Replacing pork with bell peppers is a very strange idea. The go-to cheap, healthy and easy alternativeS are found in all sorts of beans meal like read beans and rice
