I have not done the IAH-CDG in BF.
however, I have done EWR-NRT-EWR in BF. Always order vegan meal.
In these flights, my meal has always had a salad as an appetizer and then, a different salad (as the salad!). Followed by the meal.
The salads were unique to me (I did not see others getting the same).
Once I got varieties of Indian food for the whole way (EWR-NRT). It was awesome, but this has never been repeated unfortunately.
This past month, I got half of a guacomole as the appetizer!! Thats it.
(of course it looked "cool" with all the leaves surrounding it).
