The recipe makes 2 sandwiches.


  • 2 large portabello mushrooms (or 4 smaller ones)
  • 1 Tbsp olive oil
  • 1 Tbsp butter
  • 1 Tbsp miso paste
  • 4 slices of your favourite sandwich bread
  • 2 Tbsp mayonnaise
  • 1 large ripe tomato, sliced
  • 4 large leaves of crunchy green lettuce
  • 1 small avocado
  • Juice of ½ lemon
  • Salt and pepper, to taste


  1. Slice portabellos into chunky strips.
  2. Heat oil and butter in a large frying pan over medium-high heat.
  3. Add portabellos and cook, tossing them often until just tender and golden brown.
  4. Add the miso paste and toss to coat them well. Remove from the heat and set aside.
  5. Spread a thin layer of mayonnaise onto two slices of bread.
  6. Top with lettuce and sliced tomato.
  7. Season the tomato.
  8. Top the tomato with miso basted portabello slices.

Sandwich tip:

Wrap the sandwiches tightly in baking or wax paper. Tie with a string. Slice in half and then eat easily without losing any goodness!
