The Mad Italian here has a meatball sandwich with pizza sauce on it. It’s not bad at all.
Ah, that was my second favorite.
When I was a grad student at Penn, lunch was either a pizza-steak, a meatball sandwich, or a kielbasa from Frieda’s truck, or something from the Lebanese or Vietnamese lunch trucks down near the U.Penn Hospital.
When I went back on sabbatical two years ago, Frieda was still there, but you had to trek to the west end of campus to get good Lebanese food. (And I didn’t find good Vietnamese street food.)
