Ingredients

  • 4 tbsp of nutritional yeast
  • 750 g of portobello mushrooms, approx. 12 mushrooms
  • 6 tbsp of houmous
  • 1 large handful of baby lettuce leaves
  • 2 sweet potatoes, peeled and cut into 3cm chunks
  • 400 g of kidney beans, drained and rinsed
  • 2 vegetable stock cubes
  • 150 g of red split lentils
  • 300 g of oats

Method

  • Step 1

    Preheat the oven to 190°C/170°C fan/gas mark 5. Start by putting the lentils and sweet potato in a large saucepan. Cover with cold water and add the stock cubes. Bring to the boil and cook for around 25 mins - until the sweet potatoes are soft and the lentils still have a little bit of bite. Drain in a colander and then place them back into the empty saucepan, put the lid on and leave them to steam dry.
  • Step 2

    Wash and de-stem the mushrooms, place them on a roasting tray with a generous drizzle of olive oil and then cook them in the oven for 25 minutes.
  • Step 3

    Mash the red kidney beans in a big mixing bowl. Add the lentils and sweet potato and mash again until it's all combined but still a little textured. Add the nutritional yeast and season well with salt and pepper. Now, stir in the oats until you have a mixture you can shape with your hands – if you’ve over-mashed you may need to add more oats than stated in the recipe.
  • Step 4

    Shape 6 patties out of the mixture. In a large frying pan, add a little olive or coconut oil and cook three patties at a time for 3 minutes on each side until golden brown - repeat with the rest of the patties. Transfer them to a flat baking tray and finish cooking them in the oven for 10-15 mins. Remove the mushrooms from the oven once they're soft.
  • Step 5

    To serve, spread a dollop of houmous onto 6 of the portobello mushrooms (on the inside) and then put them back into the oven for 3 minutes to melt the houmous. Then, add a burger patty and some lettuce leaves – add sliced avocado or plum tomatoes too, if you like, and enjoy!
