I work 40 to 50 hours a week, and am currently working on my doctorate. I have fallen in love with steam bags, I tend to over eat when I cook on the stove. Using the steam bags I measure and weigh everything and steam entire meals. I have also started steaming my lunch, I have never packed my lunch.
Most meals are complete in about 5 to 7 minutes, this is also wonderful for frozen foods. I have seen many complaints about the cost of the bags and there is no comparison to the energy saved and pots and pans to wash.
