Speaking to BBC Radio Norfolk, he admitted he had never dreamed of going from international rugby to burgers but had found it “a really nice way to spend the weekend”.
“That’s the way of the world, and farming at the moment – diversification is the key thing to our business,” he added.
“It’s been fantastic welcoming so many families enjoying the countryside.
“There’s a bit of a disconnect in the countryside at the moment, and I think getting kids on farms is really important.
“If we can get them down here and enjoy a good local burger from a conversation with a parent, that leads on to good examples of what we’re doing on our farm to help nature and all sorts of things.”
The new venture is a partnership with cousin George and a professional caterer, with “all the family” helping out with the stall, the bar and chatting with customers.
That included England’s most-capped player Ben, 36, who retired from Leicester Tigers last season.
“He usually pops down and has a look, has a burger and brings the kids,” said Tom.
“It’s been nice for kids who love rugby to come down and get an autograph.”
