The Ultimate Christmas Vegan Burger

Preheat the oven to 220°C/ 200°C (fan)/ gas 7

Chop the potatoes (skins on) into chunky chips, then add them to a baking tray with a generous drizzle of vegetable oil and a pinch of salt and pepper

Sprinkle over half the dried sage (save the rest for later!) and give everything a good mix up

Put the tray in the oven for 30 min or until golden and crisp

Meanwhile, boil a kettle

Trim the Brussels sprouts and chop them in half, then add them to a food processor and blitz for 30 secs or until finely shredded

Tip: Don't have a food processor? Slice them finely instead!

Add the shredded sprouts to a colander and pour boiled water all over them until bright green and wilted, then set aside to steam dry

Slice the baby button mushrooms finely

Heat a large, wide-based pan (preferably non-stick) with a generous drizzle of olive oil over a medium heat

Once hot, add the sliced mushrooms with the smoked paprika and a pinch of salt and cook for 3-4 min or until softened – these are your 'bacon' mushrooms

Add the 'bacon' mushrooms, wilted sprouts, mayo and mustard ketchup to a large bowl

Season with a pinch of salt and give everything a good mix up until fully combined – this is your sprout slaw

Reboil a kettle

Line a baking tray with baking paper

Add the ultimate vegan burger patties to the tray and put the tray in the oven for 10-12 min or until cooked through

Whilst the patties are cooking, the vegetable stock mix in 250ml [450ml] boiled water

Add 1 tbsp [2 tbsp] olive oil to a pot over a medium heat

Once hot, add 1 tbsp [2 tbsp] flour and cook for 30 secs until a sandy paste has formed

Add the vegetable stock with the Marmite and remaining dried sage and cook for 4-5 min, stirring occasionally, until thickened to a gravy-like consistency – this is your gravy

Once the patties are cooked, remove the tray from the oven and top each patty with a cheese flavour slice – these are your cheesy vegan patties

Add the brioche buns to the other side of the tray

Return the tray to the oven for 3-4 min or until the cheese has melted and the brioche is warmed through

Cut the warmed brioche buns in half
