Kefta Bil Tahini

I really think there is nothing better than Middle Eastern food (aside from Mexican). I've replaced the potatoes in this recipe with beans (a 4 bean mix, to be precise, as I had no potatoes on hand).

1/2 kg lamb mince
1 large onion (1/2 diced, 1/2 sliced)
breadcrumbs (I used italian and omitted spices below)
1 egg
spices

Mix above (only diced onions) together and form into patties, then brown under grill.

3 tbspn tahini
water
lemon juice
ground pepper
garlic powder
potatoes, slice thinly

Place potatoes and sliced onions in bottom of casserole dish. Place kefta on top, then pour tahini mix over. Cook in 180C oven for 30 minutes. (If using beans instead of potatoes, serve over rice.)
