If you want to take your picnic lunches to the next level, look no further than the Classic Legendary Food Jar from Stanley. Not only can you load up the 1 quart jar with soup or stew, you can be a little more creative and tip in gravy or scrambled eggs or anything else you need to keep warm. With a warmth rating of 20 hours, you can heat up your dish in the morning and it'll be the perfect temperature for a mid-hike lunch or swing-shift dinner.
