Chimichurri Sauce: In a food processer add the garlic, parsley, olive oil, red wine vinegar, lemon juice, oregano, cayenne pepper, salt and black pepper. Blend it all together to create a nice thick green sauce. You can dice by hand if you don't have a food processor. Set to one side.
Mashed Potato: Cook the potatoes as you would normally. Then mash into a smooth consistency with a little seasoning. Add the chimichurri sauce. Cover with foil and keep warm whilst you cook the apples and black pudding.
Apples: Add butter to the frying pan followed by the apples. Sauté for around 5 minutes until softened then add 2 tablespoons of brown sugar and a dash of water. Keep the heat on high as you want them to caramelise. Once the sauce starts to bubble and takes on a dark brown colour take off the heat and set to one side; keeping warm.
Black Pudding: Rub a little olive oil on the 4 slices of black pudding then place in a hot frying pan. They will need around 2 minutes on each side, you are looking for a nice charred effect.
To Serve: Place some mash in the middle of the plate then a spoonful of the caramelised apples on the mash and finally a slice of black pudding on top and a sprinkle of diced parsley.
