This is Day 3: Dinner, on the 21 day Wonder Diet. You can use any firm fish that is n season for this recipe. Sumac is a type of Middle-Eastern Spice, available from supermarkets. You can cook the fish without it if you like. The first time I made this recipe, I was unable to buy sumac, so I used a Portugese spice blend instead.
