Healthy snacks for work place

Hi ILs,

Can you suggest me some healthy snacks which I can prepare and give to my husband to take to office . His office is quite far from home and he eats all fried food at office for evening snacks, I tried giving him fruits but those come back as it. Can you please suggest something healthy and tasty which I can give him , also if I can make it a day before it would be great , since I am also working.
