The co-founder of fresh food firm McEvoy Family Foods was dismissed from the show following a poor performance and poor sales figures in the latest challenge on the popular programme.
She was only able to sell £10 of goods at one of the second-hand shops the contestants were tasked with opening and running.
Lord Sugar subsequently accused her of showing no signs of being a great businesswoman.
But McEvoy claimed that she was better in a business-to-business environment and uncomfortable selling products she didn’t believe in.
She said: “I have to be passionate and believe in what I am selling. Perhaps that makes me a bad saleswoman as I am just really honest.”
Despite the admission she has vowed to prove Lord Sugar wrong. Currently, her Irish-based firm successfully produces own-label soups for supermarkets, including national retailer SuperValu.
She co-founded the firm with her husband in 2009 and it now operates a 1,393 m2 purpose-built factory in Clonmel, Tipperary and employs 18 people, according to SuperValu.
