1 tbsp. fresh snipped parsley
1/4 tsp. salt (optional)
1/8 tsp. ground pepper (optional)

Remove from microwave and serve with sliced tomatoes on top. This recipe may also be made in a conventional oven at 350 degrees for 20-25 minutes. The sliced tomato may also be placed on top of fish after baking and broiled on fish, approximately 2-3 minutes.
