Good, Healthy, Brown Bag Lunches?

I'm new to corporate America, and I have developed a bad habit of eating out nearly every day for lunch. To make matters worse, I'm in the loop (right off the Quincy stop), where there aren't really ANY healthy options anywhere near me. I would like to start bringing in my own lunch to save a little money, and to try to eat a bit healthier. Anyone have any favorite sandwiches or salads that they like to take into work? I was thinking about going to a local meat/cheese shop and getting a few combinations to bring in throughout the week. And if anyone knows any good places around the Quincy brown line that I may have overlooked, please let me know. Thanks in advance!
