You can pick recipes that don't need to be reheated, like bean salads! I know your saying, but I was asking about container, well this way you don't need to get containers that are capable of going from cold to hot! Should be less expensive.
Take a look at Bean Board site, they usually have recipes you can print off.
I go from dry beans, soak them over night, batch cook them, there's more nutrition in them that way.
