sleek little pot (actually, not so little - it holds 4.7 quarts!) and its thermos container. ($149.99, Gately's) Cook a full meal in the pot, then put it into the handled thermos for easy transportation.
It's a little large for brown-bagging it, but great for office potlucks and toting a pot of soup or paella across town. We really like the double lids and their no-spill, no-leak guarantee.
