Healthy Lunch in Midtown West
Better Burger is great for healthy fast food. It's got great baked fries, high-quality beef, tasty smoothies, good chile, and the soy burger's great. Burger 'n fries place without the grease. On 49th and 9th, kind of a haul, but they deliver. .
Energy Kitchen runs on the same idea as Pump. There are two locations nearish you:
417 West 47th Street
(btwn 9th and 10th Ave)
1089 Second Avenue
(btwn 57th and 58th St)
It's a bit of a walk (but that's healthy, right? =) Both Energy Kitchen and Pump deliver and are on Seamlessweb.
If you like Japanese, there are folks who sell bento boxes (non-sushi) across from the Au Bon Pain on 50th just west of 6th. Make sure you show up at 12:30 pronto, though, because they go fast. Of course, there's sushi, too. Shimizu on 51st near 8th is great.
There's an Israeli salad bar called House of Pita on 48th between 5th and 6th. Don't get the falafel (mediocre); focus your attentions on the salad combo plate and pick three or four of around 30 tasty salad options (including roasted eggplant, tabouleh, shepherd's salad, pickled red cabbage, chickpea, etc...), almost all of which are very healthy. The salads come with pita.
For Indian, Kati Roll (basically wraps made out of paratha and fillings of your choice) is fairly healthy. There's one at 46th near 6th.
