well you bring meatballs, so there's hope after all (there's nothing healthy you can bring on the go that you can buy in a store in a box)

If you can bring a package of oatmeal and a small container for liquids you can have oatmeal. I bring eggs to work - try that. Also as others have mentioned, bring veggies.
