Excuses. If money is a problem, pack lunch. You can eat cold food and won't die. You can pack sandwiches. You can use a food warmer to keep your food warm. Eat breakfast before you leave, eat lunch at work, have some snacks in your bag. Your main cost will be transportation. Outside of that, wear the same old cloths as much as possible, do your own laundry if you have a washing machine. You will trade time for money. You will have to spend time cooking, packing lunch, washing cloths and ironing. That's a small price to pay if money is tight.
