Bethesda (Stromboli and Moby Dick)
I haven't been to them in a while, but before I decided that eating nothing but cheese for lunch was a bad idea I would always get the calzone at Stromboli that, I think, is called the Stromboli. It was cheese and cheese and spinach and garlic, served with a little pot of marinara sauce on the side. I've had friends who always ordered the Miss Piggy, which I think had sausage.
I've seen other reviews on here of Moby Dick, some good, some bad; you can search them. It isn't the greatest kebab in the world but it's fine, and inexpensive for Bethesda. When I go there I get the chicken kebab and these great big pieces of naan.
The other good thing you're probably driving past is the felafel truck at the Farmers Market, about a block north of that.
