While a lot of these tricks will work with a 5 yr old do note the OP child is 16! If they can't eat at home they will simply go to someone else's house and while saving money for the OP it becomes quite tedious for the other parents to always be feeding another teen. They will "hang" out at a friends house instead of home if snacks are hard to get and I would rather have mine home. They also will just go buy their own snacks and I would rather have my DD using her money for better things than food.
By 16 the child needs to be self regulating concerning food because your time to do it is over and they really will be totally out of your control within 2 years and during these years there are a lot bigger battles and problems I'm concerned with than snacks.
