Tripe may have been a cheap way to get your protein 30-40 years ago, though I don't think that is the case nowadays. Who eats tripe now? Do you? If you do then my hat goes off to you, sir/madam! Although I could be wrong since Wikipedia gives an extensive list of dishes that feature tripe, it seems to be a dish that is widely eaten in many countries.
Personally, I do not like the texture of tripe - soft, spongy, it sets my gag reflex off. However it does absorb flavour well, I'll give it that. Here tripe has been paired with a creamy sauce and plenty of parsley. Let me know if you do happen to eat this (and like it!) or you had a crack at making it. You will forever be my hero.
