another chickpea casserole

we made this chickpea casserole so long ago that i don't remember where i found the recipe or much about it, really. from the picture, i can guess that it contains some or all of the following:

• chickpeas (actually, i know that from the title)
• brown rice
• some sort of tomatoes
• onions (?)
• spices

i do remember that it has tahini in it, to make it creamy, and some lemon juice for tanginess. we had to whisk up equal parts tahini and water (2 T?) to make a fluffy, creamy mixture. when cooler weather rolls around again, i'm going to wish i had this recipe, so maybe i'll find it again then.
