The eight-year-old competition aims to inspire and educate young people, and this year, original entries for two must be created, using Red Tractor beef and lamb, for less than £10.
Martin will pick one of the finalists as the 2013 national champion, and the winner will get an all-expenses-paid trip to London to take part behind the scenes at Saturday Kitchen.
The winner will also be dining at two of London’s finest restaurants and meet distinguished chefs.
James Martin said: "I’ve judged the Make it with Mince Challenge for eight years now and, each year, the standard really does get better and better."
"We see kids as young as 11 years old making their own pasta, baking bread from scratch and creating innovative and often unusual dishes. It’s a joy to watch young people cook like this at our regional finals and I can’t wait to see the dishes our 2013 entrants create over the coming months," he added.
Last year’s winner was offered an eight-course tasting menu by Michelin-starred chef Alain Roux and was introduced to one of Britain’s most highly respected chefs Michel Roux.
All entries must be submitted before 18 October.
