Have you encountered andouillette? If you are seeking to eat cheaply in France you may well encounter it, but avoid it at all costs. It is a tripe sausage with added morsals of intestine. It looks grim and smells appalling. I imagine humble pie must be similar. Andouillette is not to be confused with andouille, which is OK. I have never eaten haggis, but I have my suspicions!
