1. Pre heat the oven to 180 degrees. Place the potatoes into an oven dish and cover with ½ a tbsp of olive oil. Sprinkle 1 tsp of smoked paprika, salt and pepper all over and mix together until all chips are covered. Make sure the chips are all flat and layered evenly. Pop it into the oven for 20 mins.

2. Meanwhile drain the tofu and press out any of the liquid by wrapping it into a piece of kitchen roll. Place the tofu in a bowl and crack in the egg, followed by the breadcrumbs and marmite. Give everything a good mix until it looks like scrambled egg! Then shape the mixture into 2 even-sized patties.

3. Remove the chips out of the oven and turn each chip over keeping them layered evenly. Place back in the oven for a further 20 minutes. With 15 mins to go until the chips are cooked, place the burgers in the oven for 10 mins flipping halfway through.

4. Remove the burgers from the oven, heat the remaining amount of oil in a non-stick frying pan on a medium heat and fry each one for 2 mins on each side until lightly golden. Fry the red onion whilst the burgers are cooking.

5. Open each bap, place the burger on first followed by the cheese, beef tomato, gem lettuce and red onion and serve with the chips on the side.
