Don't let something like the need for carrying/transporting your food horizontally discourage you. That's easy. You have a lot of options for on bike carriers multiplied by endless containers. You got Wald folding baskets, a rear rack with trunk bag, a rear rack with a pannier and hundreds of different size tupperware containers that will fit (and stack) neatly inside your pannier. You have a flat front basket or a front rack with a cooler strapped down.
This is nothing to throw the towel in for and the finding the right solution for you can even be fun.
