These swordfish steaks bake to perfection with a colorful combination of tomatoes, mushrooms, celery, onions, and bell peppers. It's a creole-style dish with a dash of louisiana spice for flavor. While swordfish is a delicious and nutritious seafood choice, it does have a higher level of mercury than most species and should not be eaten as frequently. Because mercury can harm the nervous system of unborn and small children, the u. S. Food and drug administration and the environmental protection agency advise that women who may become pregnant, pregnant women, nursing mothers, and young children avoid eating swordfish and other fish high in mercury. This recipe makes enough for 4 people, but can easily be scaled down to make an elegant dinner for 2. Serve the swordfish steaks and vegetables on a bed of rice or serve them with roasted potatoes.
