Oh aye, Hot Dogs/Frankfurters can certainly be the ultimate ‘mystery meat’ meal – but ‘good quality’ ones are sooo tasty! I stick with Herta for Franks, but H-D’s made with chipolatas are also excellent.
What goes into McDonald’s Chicken McNuggets doesn’t bear much lose scrutiny either (57% fat, and the US version contains Dimethylpolysiloxane, which is silicone-based). I liked them when they first came out, but within about six weeks the flavour (contents) changed and now they’re pretty horrible.
