The best thing I've found so far is reusing my Ball canning jars. I make the soup and immediately fill the jars and refrigerate them. They are a little heavier to carry in my lunch bag but all I need to do is take the lid off and heat the jar of soup in the microwave. Working great for me and I'm happy to get some use out of all those canning jars I don't normally use during winter months.
We think this is a great idea. It's inexpensive (canning jars = cheap) and this sort of glass reheats safely in the microwave. Just heat and stir in any mix-ins. Here, for instance, we show the scallions and tofu for miso soup carried separately in the lunch bag.
