Here is another time-saving Lunchbox Tip, this time from momables.com:
Tip 2:
Freeze individual portions of rice or pasta. Reheat and pack in a warm thermos for lunch.
You can also freeze individual portions of rice or pasta and reheat them before you pack lunch.
Place individual servings of rice into ziplock baggies. Try to remove most of the air, and label with the date.
Rice dishes can be frozen up to 30 days. After that, they tend to dry out.
The morning you are ready to pack the rice for lunch, run water over the frozen bag for about 15 seconds.
This separates the food from the sides of the bag, allowing it to slide out.
Place frozen portion of rice in a microwave save bowl and reheat in the microwave. (Add 1-2 TBS of water to the dish before microwaving. This will prevent any dryness.)Pack cooked rice in warm thermos and WHALA! A nice warm lunch ready to go!
