Belfast-based Mount Charles serves workplaces, schools, healthcare facilities, airports and universities.
The deal sees the company take an exclusive area development contract to roll out Freshly Chopped across Northern Ireland and Donegal.
Initially, the deal will see six Freshly Chopped outlets open across Northern Ireland’s high streets, with the first flagship store due to open in Donegall Square West in August.
Gavin Annon, head of sales and marketing at Mount Charles, said: “Today’s customer is focused on service and provenance, and Freshly Chopped, like ourselves, is an indigenous food company that uses the highest quality and freshest produce available.
“The addition of the Freshly Chopped brand to the Mount Charles portfolio strengthens our ability to deliver healthier eating choices to the people of Northern Ireland.”
Brian Lee, co-founder and chief executive of Freshly Chopped, added: “When we founded Freshly Chopped six years ago, our mission was to make it as easy as possible for people to eat healthily.
“This partnership with Mount Charles will help us to continue our journey of bringing healthy fast food to more people across the island of Ireland.”
