So i have to tell you that in Israel these are made with hot dogs ( usually chicken) and puff pastry and look like the ones lowspark posted. However, since Jews and traditionally don't eat pork, they are called " moses in a basket"
and the word pig is not mentioned.
I and my friends find that while these are definitely*kid's food* , if we serve them when we have company, grownups grab them too.
( in general, the concept of puff pastry stuffed with meat, vegetables, cheese, etc -burekas- is very popular here and can be found in bakeries, cafés, restaurants, etc)
