What cut of beef might this have been?
It was an ingredient in a beef and vegetables dish at a Vietnamese restaurant. The beef was in 1x3" wide slices and had a lot of marbling. It was tender and reasonably flavorful and had a rim of meat above the fat streaks. I would say that they usually use flank steak in their beef stir fries, but this wasn't flank. Mighten this have been the last of a cut of beef that normally goes with pho? I should have asked and now they will be closed for a month.
