This recipe is from the middle eastern cookbook by Tes Mallos. My husband is Palestinian and I have been making this for guests for quite a while, even my kids love it! This is the best recipe I have tried for zucchini or "kousa". It does take time and you will need a zucchini corer (mine was a gift from MIL). If you use an apple corer you will have to cut the zucchini into smaller segments. But this is a really wonderful dish, you could also substitute some of the zucchini for small eggplant, as this is traditionally cooked all together with both, but I like zucchini best.
