Wash peppers. Cut them longways and take out the seeds and ribs. Arrange the peppers in a microwavable-safe baking dish.
Mix meat, rice, ½ of the tomato sauce, ketchup, Worcestershire sauce, salt and pepper in a large bowl.
Fill the peppers with the meat mixture.
In the bowl you used for the meat, mix together the remaining tomato sauce, water and sugar. Pour this mixture over the peppers.
Cover the peppers with a lid or plastic wrap.
Microwave on med. high for 25 minutes. Let peppers stand for 5 minutes before serving.
