Make two ‘burgers’ per person as a meal, one as a snack.

Large flat mushrooms
Henderson’s Relish or vegan Worcestershire sauce (optional)
Bread buns
Chilli sauce or tomato ketchup
Bag of salad leaves
Olive oil

Brush the mushrooms with the olive oil and Henderson’s Relish if using. Heat them under the grill (or on a barbecue) for a few minutes on each side until tender. Serve in bread buns with chilli sauce or ketchup and salad leaves.
