a turkey sandwich has more protein unlike the potato chips. a turkey sandwich would fill your stomach better than potato chips. a turkey sandwich is heathier than potato chips for multiple reasons including sodium, and carbs.
therefore the turkey sandwich would be a better choice.
Why I think as though a turkey sandwich is better because it gives you enough protein to go throughout your day. Another reason is because i'm currently starving and I could use some food to eat. A turkey sandwich would ultimately fill my stomach up and I would not have to worry about eating for a few hours. However, with a bag of chips, I wouldn't be hungry anymore in the moment, but a few mins later I would be hungry.
