I pack my dd's lunch. I think it's 1.80 to buy at school but she doesn't like anything on the menu so that's not really an option. I send her with a sandwich (turkey or ham and cheese normally, whichever is on sale), fruit, crackers and a KK with water. I used to send more but she doesn't have enough time to
eat it all and it got tossed. I've never calculated it out but I'm pretty confident ...
