1. Place the slices of lemon side by side in the bottom of a baking dish.
2. Put fillets on top of the lemon slices.
3. Sprinkle, in the sequence listed, all the remaining ingredients.
4. Bake in a preheated 375 degree oven for 20-30 minutes (depending on thickness of fillets) or until flesh is no longer translucent and flakes readily. Low in calories, but mighty tasty! Serves 4.
