Yes, it's a slightly bigger portion of fruit than the fruit on the normal tray, melon, kiwi and pineapple usually with a small bowl of yogourt instead of the hot.

Because there are so few, sometimes just one, crew find it hard to offer them, because the moment you ask the first passenger, they have run out!
So just ask if the yogourt option is available on your next flight.

I believe BA are in the process of reviewing what they offer at breakfast on Shorthaul flights.
