Grate your veg and then give them a good squeeze over a colander to get the excess moisture out.
Put all the mixture in a bowl for the burger-dog and mash it all together with your hands until well combined.
Shape into 4 sausage shapes and chill in the fridge for half an hour.
Pre-heat the oven to 180’C
Roll the burger-dogs in a little olive oil and roast in the oven for 25-30 minutes to crisp up.
While the burger-dogs are cooking, mix together the ingredients for the sauce and cover until ready to serve.
Once the burger-dogs are cooked, place inside the buns and top with the brie, place under a hot grill to melt and then squeeze the tomato and lettuce into the side.
Top with the sauce and serve with some crispy potato wedges.
