Preheat oven to 400 degrees. Mix all of the ingredients, except the fish and opt parsley, in a small bowl. Prepare your baking sheet. Either spray with non-stick spray or use parchment paper.
Spread mixture on both sides of the fish. You can use s spoon or a brush. Bake for 10-12 minutes, or until the fish flakes easily. If you fish is a little thicker, it will take longer. Keep checking every 2 minutes.
Serve warm. Sprinkle with the optional parsley.
