Tips for packing flight attendant lunch box (3day). I have Boiled eggs and miso soup for breakfast. Lunch is tuna or chicken salad scooped with cucumbers, carrots or celery. Dinner is sliced turkey and mashed cauliflower ( not pictured). And I brought apples, peaches, cherries, figs, FiberOne bar, and seaweed as snacks. I also have milk for my tea.
