I like sprouts
well, as long as not over cooked.
I have heard that there is nothing you can do with slugs that make them worth eating, they are just too slimey to fool with. Can't say that I have tried though.
Texture wise, boiled tendon, as in soup or stew, that gelatinous crunch just turns my stomach.
I reckon that as far as contents goes, tinned sausage is probably the nastiest thing you could eat while in the field. Mechanically separated chicken is a lot worse than almost any grub you could find!
