Stuff Your Own Falafel Sandwich at Amsterdam Falafelshop (Somerville, MA)
As far as cheap eats in Boston go, it's hard to beat Amsterdam Falafelshop! For a small falafel sandwich, you'd get out with under $6, or $7 for a regular size. You can get it as a bowl, too, but I think the sandwich is the way to go. First, choose between white or wheat pita, which comes toasted then stuffed generously with those crispy chickpea falafels. That's it? Not at all. Next, you can peruse the toppings and fill it with whatever you want. Whatever. You. Want.
