Homemade sandwiches, my out-of-office tactic I suggest to everyone I meet. Pack a sandwich, a snack, a piece of fruit and water when traveling or working from a remote site. Taking time to buy lunch is annoying and finding healthy food on location is problematic. Homemade sandwiches are healthier than store-bought and kinder on the pocketbook. See my pull down menus for my favorite sandwich recipes.
P.S. Make enough sandwich fixings to last the week.
