The sausages thing just shows how out of touch she is. The problem isn't that they contain "bollocks and eyelids", the problem is a) those were not happy pigs and b) they are 68% water and assorted filler.
I buy mostly local produce, largely for political reasons. I'm sure my sausages contain some unappetising parts of the pig. I don't care - I'm a meat eater, it would be hypocritical to kick up a fuss. Plus these sausages are a hell of a lot more than 32% meat, taste great, and are very filling. They don't cost the earth either - and because they are not full of water, they stretch further. Same principle as buying mature cheese rather than mild, as you don't need to use so much.
To then say that any sausage is better than no sausage? No. Hell, my student cookbooks used to advise avoiding the cheapest nastiest meat, and that was over a decade ago. If you genuinely can't afford slightly more expensive sausages (NB Jack, you don't fall into this category), there are lots of cheap alternatives to get protein into your diet.
But she's back to her weird reverse snobbery about being too poor to enjoy fancy ingredients like ethical meat or arborio rice or salt. This phase rolls round a LOT.
