Hi Mary,

 >This reminds me, In South America I used to buy chicken intestines to feed
 >my dog.

Which country was that, please? I left my heart there. In Colombia we ate
Mondongo soup which was tripe in a tomato based soup. It was delicious.
Here is one recipe:

I did a search on Mondongo and there seems to be a recipe for most Latin
American countries.

Paleobest,
