You don't even need to make it at home. I used to just but all my stuff on my way into work on Monday and store it in my office. Most of the stuff we put in sandwiches (bread, butter, cheese, cured meats, pickles, condiments) will last a week or more in an air-conditioned office. Just store it in an air-tight container and give it the smell test before you eat it.
