Ham and Cheese Panini is always my pesonal favourite. I also like how Ryanair with a lot of the snacks go large eg. Twix Xtra or Mars Duo as oppossed to the regular sizes like on EasyJet and charge the same amount!
Flew with EasyJet recently and thought there was a real lack of choice and by the time they were half way down the cabin, they had ran out of all hot food and ran out of vegetarian options by 1/3 of the way down! Luckerly I was 8 rows from the back, so just made it!!!
