My husband, who is diabetic and has to watch his carbs, and myself, who watches her calories go to subway BECAUSE their sandwiches are not massive. They have a lo-carb wrap that you get substitute for the bread as well. While the meat portions are not huge, we have all the veggies added to add to the bulk and flavor of the sandwich. And we have them leave the dressing off.
But that's just us, people who are concerned about the healthiness of what we eat.
Of course, don't add cheese, salt, and high fat dressing. What's so hard about that? I am so tired ot these "super size" Nazis.
