Insulated Lunch Containers for Hot Food

Insulated Lunch Containers for Hot Food

Last week the heater went out in my truck, my only vehicle.  My commute usually takes 40 minutes in good traffic, which is not so bad.  The problem is the cold weather.  I did not have any good insulated lunch containers for hot food.

By the time I get to work my lunch is always cold.  I was already chilled from the drive in and did not relish the idea of eating my lunch cold.  I could temp the office microwave which only cooks on one setting, emergency room hot.  A bit of an exaggeration, I don’t like using microwaves and think food taste better heated on a stove.  So I had to get creative until my next paycheck.

After of week of trying to be creative I was tired of fighting a losing battle of keeping my lunch warm and finally broke down to find the best insulated lunch container I could find that would help keep my lunch nice and toasty.

There are so many insulated lunch containers to choose from, I was able to narrow it down to these top five.  I’ll let you guess which one I picked (here’s a hint; it’s not the one with purple hippos on it)!
