I packed this for an outing today, one tier for each of us.
My husband's tier is a ham and cheese sandwich on multigrain bread, a hard-boiled egg and some bell pepper slices. Toddlebug had a PB & J tortilla, a chocolate zucchini mini muffin and a fruit cup. I had cranberry-walnut bread, a hard-boiled egg and peas.
Because our options for buying food would've been very limited, the tiffin basically pays for itself in just one use like this.
