I'm not sure when this started happening, but Subway is now offering "Mini Subs." There's nothing special about them except they happen to be about half the size of a regular 6-inch sub. Since I was still hungry after my soup today, a small sandwich was just what I needed! According to Subway's site, they offer them in Tuna, Ham, Roast Beef, and Turkey. Excepting the Tuna, they're all 3 points*.
All in all, I'd say they're a great snack and perfect for a pick-me-up. I wouldn't go so far as to say it's a whole meal, but with soup, definitely. If you don't see them on the menu board, just ask. I only knew they carried them because I happened to see it on their website today.
* This is of course for a sandwich on whole wheat bread, lots of veggies, and no cheese or condiments. Visit Subway's site for detailed nutritional information.
