I have been packing Bento boxes for my kids in advance for a while now, but I just started making them for my spouse too! For my husband, I send a charcuterie snack box packed in a glass, bento box, I like the walls which help keep things in place. This is also handy for separating dry or crispy ingredients and wet/chilled ingredients. For the kids, I double up and prepack the majority of their lunch trays, and add one extra component like a croissant or sandwich the morning of school. Their bento boxes are my favorite because there is a built-in ice pack tray. It keeps the cold right there as close to their food as possible, ensuring their lunch is served at a safe temperature. This is important because we are in hot, hot hot Texas. to save myself some time, and an especially when I have shopped in bulk at Costco, more than one days worth of lunches at a time, there are spare trays that come with snap on lids and then you just snap it into the lunchbox shell on the next day.
