To answer the earlier question, I ordered whatever the meat-based dish was each time. There have only ever been two options avialable - either chicken / beef dish, and then a pasta-based one.
On a related note, is the second meal PE specific? You don't get a choice, but it appears more extensive than the Y sandwich etc you'd normally get. It is also different from the C meal, which this last flight appeared to be a bbq sandwich or a salad.
In PE, it was a "burrito bowl."
