At work 5 days after food poisioning - what can I eat for lunch?

[Overseasmom100]

So 5 days past now...have been eating small amounts of toast and plain rich tea biscuits plus a bit of banana. Today at work have no food apart from the rich tea but feel quite light headed and feel I need something more. Any ideas? I will need to nip to the shops though to grab something?

Sandwich? Cheese biscuits/ crackers, baked potato, soup and a roll?

Do you have a microwave? If I have an upset stomach I get a 2 min express rice pouch which fills me up but doesn't aggravate things!

Plain bread?

A roll and a slice of cheese from a supermarket deli?

ooo didn't think dairy/cheese would be ok? I was thinking of a rice pouch
