Elsewhere, Simon shared a picture of himself excitedly poking his tongue out for the camera as he cooked for customers at his Greens restaurant in Manchester.
The TV presenter was quick to react to a fan on Twitter, who queried his lack of ageing over the years.
In view of his 271,000 Twitter followers, he wrote: “Here we go full house @greensveggie tonight.”
One of his fans commented: “Good luck – and do you NEVER age? x.”
But seemingly disagreeing with the latter, Simon replied: “I looked old 20 years ago Lyd x.”
Sunday Brunch continues today on Channel 4 at 9.25am.
