I need to get my budget under control

Most of my budgeted amounts are in line. But my biggest budget-buster is food. I think that holds true for a lot of people. I don't remotely cook so I eat most of my meals at work. At home I have easy things like pasta or rice and beans. I still spend about 10% too much each pay period. Paying for school leaves me no extra money so I need to get this under control sooner rather than later.
