Aldo Zilli, who is the chef/owner of Zilli restaurants in Soho, said that he would like to see more prawns, squid, sardines and mackerel on the nation's barbeques.
According to health experts, people should consume at least two portions of fish a week - including one portion of oily fish.
"Those kinds of foods are good for you and also healthy and inexpensive," the chef revealed.
Mr Zilli said that people should keep their barbeque recipes simple and ensure they always cook their meat thoroughly to avoid food poisoning.
He advised: "You can't be taking a chance here with food - especially chicken - so cut through it and make sure that it is cooked or finish it off in the oven if you have to."
According to BBQ.co.uk, more than one in ten British people claim to be fans of year-round barbeques regardless of outdoor temperatures.
