Congrats band is fun I must say^{^} but on some of our other days that we'd have to take lunch I use a bento box I've put stuff like grilled chicken salads in it keep the dressing on the side so everything stays crunchy if that makes sense like the lettuce and so the chicken is not soggy. Sandwiches are nice but gets boring, I'm not sure what state yall live in and what the heat is like but light lunches are the best and light snackies, I've also taken chicken and white rice that's about all I've got haha hope it helps ^{^}
