Posted for Back to School Photo Tag Lunchbox Special When cooking with a thermos bottle, it is important to use a thermos that will hold heat the longest, and last the longest under heavy use and abuse. This recipe is based on a 1 Qt Stanley Food Thermos. The food thermos has a wide mouth lids with an insulated lid that doubles as a bowl. You made need to adjust the amounts to fit your thermos.I had a quick question - the spaghetti is placed dry in the thermos? Thanks! I would love to try it for my son's lunch but want to ensure that I make it correct :) If this works, I will give it 5 stars for simplicity as well. Thanks!Heck, I'm giving this recipe 5 stars for the sheer simplicity! It also happens to taste really great, too. :) I don't know why I have never thought of doing this before. Soup with no stove cooking? Yes please. Thank you for a fun lunch idea!
