A Greek (or more generally Balkan and Turkish) delicacy consisting of vine leaves stuffed with various things including rice.
The ones I've been eating just now are vegetarian, and also contain tomatoes, onions, parsley, mint, olive oil, tamarind, and other spices and seasonings; but they may also contain meat. Other leaves may be used in place of vine, such as cabbage.
The Greek plural of dolma is dolmades.
I don't know what it originally was, but further investigation shows that in Turkish the dolma part means anything stuffed. Stuffed vine leaves are yaprak dolma, stuffed pimentos are biber dolma, and stuffed mussels are midye dolma.
