You will get a "hot breakfast" in that it will be hot and will be food consisting of breakfast. That's different to a full hot breakfast, which is a full English breakfast. I think it'll be something like the domestic pannini served on LHR-MAN and NCL. You will also get a drink from the bar and a choice of tea or coffee.
And witness one of the most "expedited" cabin service you will ever see in your life -other than a full Club cabin on a 3 crew A319 JER-LGW breakfast flight, when they basically have to throw it at you as they walk down the aisle, wheel the trolley back to row 1 and whisk it away again!
