Tips for bring your own lunch:
1 – Unless one drives to work, the lighter and less bulky the better. Oh, and leak-proof bags are a must.
2 – The more moist the sandwich contents, the soggier the bread is by lunchtime. Either use dense bread (pita), assemble the contents on the spot or avoid sloppy-joes altogether.
3 – Co-workers (co-lunchers?) don’t appreciate overpowering odors. Avoid strong cheeses (Limburger, anyone?) and similarly “aromatic” salad dressings.
4 – If it leaves a noticeable shirt/tie stain, leave it home (skip the left-over spaghetti and meatballs, spare ribs and shpritzy half grapefruit) or bring a bib (napkins? hazmat suit?).
5 – Afternoon coffee & cream drinkers most likely avoid fleishig lunches as a rule.
