I saw this in the frozen food section of the store here and wondered what it was. When I got home I found here (http://en.m.wikipedia.org/wiki/Mulukhiyah) that it was:
"the leaves of Corchorus species (Jute leaves) used as a vegetable. It is a popularMiddle Eastern and North Africancountries. Mulukhiyyah is rather bitter, and when boiled, the resulting liquid is a thick, highly mucilaginous broth; it is often described as "slimy," rather like cooked okra. Mulukhiyyah is generally eaten cooked, not raw, and is most frequently turned into a kind of soup orstew, typically bearing the same name as the vegetable in the local language."
