Best Veggie Sandwich in Town?

My office provides free lunch everyday, which is a tremendous money-saving perk. Usually it's healthy and at least fairly good, but there are the inevitable days (e.g., pizza Fridays and occasionally less-than-desirable options on Wednesdays, which changes from week to week) when buying something separate becomes warranted. Given the fact that I'm not paying for lunch the vast majority of the time, it's a little easier to justify indulging in a perhaps slightly overpriced - but so worth it - sandwich or salad from one of the great local spots near the office once in a while.Friedman's Lunch in Chelsea Market  right across the street is consistently solid - the food is fresh, healthy (mostly) and really tasty. The downside is the price. But, once every couple of weeks I'll get something from there, and my most recent go-to is the Garden Vegetable sandwich: grilled sourdough with hummus, avocado, sprouts, cucumber, tomato, carrots and lettuce. The freshness of the ingredients, char on the bread and quality of the hummus makes for a fantastic combination of flavors and textures. I would happily eat it every day if I could!As a more wallet-friendly alternative though, I think I need to attempt recreating this at home.
