The challenge is for chefs to have not just their vegetarian dishes perfectly considered but all their accompanying vegetables as 'heroes' on the plate.
Mr Scott said this year's innovative entries really showcased the true potential of vegetables.
"It is great to see the variety of vegetables used to make up the dishes, all with careful consideration for textural contrast, nutritional value and balance. New and exciting styles of presentation are apparent with some previously overlooked vegetables getting their chance to shine.
"Diners are looking for at least one high quality vegetarian offering as a starter and main course and gluten free, diary free and vegan dishes are considered a must in any professional kitchen.
''The challenge is for chefs to have not just their vegetarian dishes perfectly considered but all their accompanying vegetables as 'heroes' on the plate. We are fortunate to have a fabulous choice of vegetables available so let's make the most of it."
