Vegetarian for lunch near Prudential Center
There are a couple of vegetarian sandwiches and other options at Parish Cafe on Boylston and Pops in South End. Mela in South End also has many vegetarian options, but I personally prefer stronger flavors for Indian food. L'Espalier is also reasonable during lunch and has a nice risotto. Also in South End: Flour, Orinoco for Venezuelan, and Petit Robert on Columbus.
