This quick, easy and delicious recipe for baked fish with tahini sauce is a favorite in my family. It is a variation on a classic middle eastern-north african recipe, with a few touches. Choose a white fish like snapper, tilapia or halibut. Weve also made this with wild salmon. The tahini sauce will easily keep for a week, so save any leftovers for salads, sandwiches, topping steamed rice or dip for veggies.
