A very tasty recipe from the 'Good Food for Friends' cookery book using tuna, eggplants and cherry tomatoes. The baba ghanoush can be prepared earlier in the day and kept covered at room temperature. The baba ghanoush also goes well with other robus-flavored fish such as swordfish or red mullet. The recipe is for 6, but it can easily be adapted for 2 or 4. Serve with buttered spinach and/or potatoes. (This recipe is labelled as Middle East in the Zaar World Tour because of the Baba Ghanoush).
