I work from home so I don't "bring" lunch but I do travel and have to carry food for that day on planes etc. Here's what works for me for travel and also some things i used to carry for work:
1. Jerky. Never spoils, can eat for snack
2. lunch meats. I know they can be high in sodium and nitrates but they're easy to eat and portable.
3. Baby bel cheeses of different sorts
4. Edamame
5. Little chicken or beef meatballs that have been cooked so you can reheat at work.
6. Leftovers from dinner. When I used to work in an office outside, instead of putting away leftovers in the fridge, I'd pack two lunch boxes and we used to eat those for lunch the next day.
7. Hummus with veggies (if you can eat veggies now, I'm still not there)
8. Omelette made the night before and rolled, cut into slices.
9. Boiled shrimp
10. Boiled eggs with some mayo on the side
11. chicken salad
12. Egg salad
13. Greek yogurt
14. Almonds if you're allowed nuts
15. Egg quiches made in muffin tins
Hope that helps!
