This is from The Cooking of the Eastern Mediterranean
1 pound fish
1/2 tsp salt
1/4 tsp cayenne
1 T lemon juice
Combine in a baking dish and put in the fridge for an hour, if there's time.
Meanwhile, cut an onion into quarters or eighths and cook in 1-2 T olive oil till it's golden brown, about 15 minutes.
Also, make some tahini sauce. In a blender, combine 1/2 c tahini, 2 cloves of garlic, 1/2 tsp salt, 1/2 cup lemon juice, and 1/2 cup cold water and blend till smooth.
Heat the oven to 375. Cover the baking dish with foil and bake for about 10 minutes. Pull it out of the oven and cut the fish into bite-sized pieces. Stir in the onions and top with the tahini sauce. Bake for 15 more minutes.
This is really yummy with carrot salad. I usually serve it with couscous, or maybe rice.
