Prep Time 15 min

Cooking Time 15 min


  • 400g can black beans, drained
  • 400g lean beef mince
  • 1 egg
  • 1tbsp reduced-salt gluten-free tamari or soy sauce
  • 2–3tsp chipotle paste
  • 8 very large flat mushrooms, stalks removed, wiped with wet kitchen roll
  • 2tbsp sunflower oil
  • 4 slices (80g) Swiss cheese
  • ½ iceberg lettuce, leaves torn
  • 1tbsp gluten-free American mustard
  • 2 vacuum-packed beetroots, sliced
  • 1 small red onion, sliced into thin rings
  • 1 small carrot, grated
  • 8 slices pickled jalapeño


  1. Heat the oven to 200ºC/fan 180°C/gas 6. Line a baking tray with non-stick baking paper.
  2. In a bowl, crush the black beans until most of them are broken but not mashed. Add the beef mince, egg, tamari or soy sauce and chipotle paste, then mix well. Using wet hands, form
    the mixture into 4 burgers.

Put a slice of cheese on each burger, transfer to the baking tray and cook in the oven for 1 min or until the cheese is melted.
  5. Top 4 of the mushrooms, stalk side up, with lettuce, a burger, mustard, beetroot, onion, carrot and jalapeño. Finish with
