Method

How to make the lentil and mushroom burger patty:

  1. Blitz mushrooms in a food processor until finely diced.
  2. Add the mushrooms to a hot pan with a drizzle of olive oil.
  3. Cook out all of their water. Work in batches if necessary to not overcrowd the pan.
  4. Scrape mushrooms into a large bowl.
  5. Add the lentils to the dry, hot pan and toast them until dry.
  6. Add to the bowl of cooked mushrooms.
  7. In the same pan, add a fresh drizzle of olive oil and cook the onion until soft.
  8. Add the garlic and paprika and cook for a minute until fragrant.
  9. Add to the bowl of mushrooms and lentils.
  10. Add the flour, breadcrumbs, and a good pinch of salt and pepper. Mix everything together well.
  11. Mash some of the mixture against the side of the bowl (keeping some of the lentils whole and some mashed gives the patty great texture).
  12. Divide the mixture into 4 to form patties. The patties will be around 180g each.
  13. Fry patties in a little drizzle of olive oil until golden brown on both sides.

How to make the avocado salsa:

  1. Place all the ingredients in a medium-sized bowl and mash lightly.
  2. Season well.

To build the burger:

  • Place the 8 portabellos on a wire rack on top of a baking tray.
  • Sprinkle with a little seasoning and roast for ± 7 minutes at 200˚C until tender.
  • Brush with a little BBQ sauce or any brown sauce to give them a glazed and shiny look.
  • Slice a little off 4 of the portobello “bottom buns” so they sit flat.
  • Top with a generous pile of greens and carrot ribbons.
  • Place a lentil and mushroom patty on each one.
  • Top with a generous amount of the avocado salsa and finish with the top portobello bun.
  • Sprinkle with sesame seeds for a burger effect and serve alongside some crunchy sweet potato fries.
