There are three safe ways to thaw a freezer meal.
1. In the refrigerator.
2. In a cold waterbath.
3. In the microwave.
(Anything thawed in the microwave should be cooked immediately
The question arises, "how can I get the meal out of the bag to microwave it?" No one wants melted plastic bag as an extra ingredient, so microwaving in the bag is not a good idea. Snip the bag a place food into a microwavable safe dish. Problem solved.
