Travel tips- any suggestions?

Hello All,

I travel a lot for work between USA and EU.

Does anyone have any tips for travel?

I’ve been managing by eating carrot batons and hummus during the summer, but not sure that will work in winter - I really feel the cold.

Any suggestions for eating clean and inexpensive while staying in hotels? And ideally warm food?

(Ps. I’m coeliac and allergic to corn/maize).

Thanks in advance.
