Eat to the Beat (ETTB) provided behind the scenes catering and support services at the Festival of Remembrance at the Royal Albert Hall in London on 12 November.
The contract caterer, which is part of Global Infusion Group, has serviced the festival since 2008.
This year, for the first time, the backstage catering specialist created a pop-up kitchen and dining area in the loading bay of the Royal Albert Hall to feed 1,100 festival participants.
The menu included shepherd's pie, vegetarian shepherd's pie and Thai chicken curry with rice.
ETTB also catered for the 260-strong BBC team and event crew from the venue's kitchen.
The festival remembered the Battle of the Somme, Battle of Jutland and the 25th anniversary of the Gulf War as well as the 80th anniversary of the maiden flight of the Supermarine Spitfire.
It was attended by The Queen, as well as the Duke of Edinburgh, Prince of Wales and Duchess of Cornwall and the Duke and Duchess of Cambridge.
Prime Minister Theresa May and Labour leader Jeremy Corbyn also attended the ceremony.
ETTB was appointed by Riverside Productions which co-ordinated the event on behalf of the Royal British Legion.
Mary Shelley Smith, global operations director of Eat to the Beat, said: "We are honoured once again to have been selected to cater the Festival of Remembrance. It was a wonderfully moving occasion with many poignant moments.
"It was quite a challenge to feed so many people in such a short space of time but our team are very experienced to deal with this sort of occasion, and the kitchen and dining facility we created at the Royal Albert Hall worked really well."
The firm had a crew of 26 on site on the Saturday including six chefs and front and back of house staff. Team members were also on site for two days in the build up to the festival to feed the BBC crews.
Earlier this month, Global Infusion Group topped a list of the fastest growing foodservice operators in the UK.
The firm went straight to the number one spot as a new entry in the 2016 Foodservice Growth report, compiled by AlixPartners and EP, after achieving 67.9% compound annual growth from a turnover of £17m.
