It might make sense for you to have a small freezer. When things are going better, make and freeze large batches of foods you like. Then you can microwave them when you need them. Google "once-a-month-cooking". This is a good project to do with friends/family, too. As far as hauling meals goes, you can pack a bag with nuts, cheese, crackers, carrots, celery, apples, peppers, oranges, pears, grapes.
