What is healthier, full sandwich or half sand and clear soup? I'm on a diet.

Describe sandwich! Come on! depends what is in the sandwich! personally why not go for a salad with a balsamic dressing? The real key is to eat enough to not be hungry. Salads and fresh veg you can eat unlimited amounts. Get full. Soup is also a great choice. I do not like the sandwich option because you should probably cut back on the bread!
