I purchased this little gem after my nutritionist showed me hers. It only weighs about a pound or so. You can keep soup or whatever you like and it will have your COOKED food piping hot for by the time you are ready for lunch irbdinner at work. I got mine on amazon for 21.00 so not horrible.
I had 2 oz chuck roast along with summer squash and roasted sweet potatoes from last night's dinner. I separate everything with parchment paper. Works great. I am a huge fan of homemade soups so this will he very handy .
