I actually took this picture before putting it in the oven, since it was so pretty (it was still pretty when I took it out, but not quite so vivid). I made up the recipe and it took about 10 minutes to prepare, plus 30 to cook.
Preheat oven to 350 degrees.
Wash tilapia filets and spread them in the bottom of a glass baking dish.
Salt fish and drizzle with olive oil.
Cut orange(s) and onion into thin slices and arrange over the fish.
Sprinkle pomegranate seeds over that.
Bake 30 minutes at 350.
Once it's served, have each person tear out pieces of the orange from the slices to eat with the fish.
