Does anyone else have trouble conceptualizing how much food will fit into the box? I have "scrap bowls" handy when I'm packing my husband's lunch, but often times I'll be lucky if I get more than a bite or two of what I've made for my own lunch. The only way I'm not scrambling for fillers is cooking with the intention of having the scraps for lunch.
Then on some days I have the interesting problem of trying to fit too much. I was going to put pasta salad, normal salad with chicken bits, and a cut-up apple. There isn't enough room for two muffin cups and much of anything else, so I must have been thinking of a retired box. I ended up spreading the planned meal between two boxes, with the chicken as a salad. (I figured between the stress and the salad, he's actually getting the right amount of calories in two boxes.)
