my dad is thinking of putting up a small business..help pls?

its like a hotdog stand where people can jst get some and eat it on their way to work...but it aint hotdog..we're thinking of rice meals to go. any ideas on packaging? it has to be CONVENIENT--for the buyers, PRESENTABLE--for marketing purposes, and of course, AFFORABLE packaging--low on cost but definitely safe, clean, etc.
