- Easy
Ingredients
- 1 red onion, finely sliced
- ½ tsp sesame oil
- ½ tbsp dark soy sauce
- ½ tbsp butter
- 2 tbsp oyster sauce (see tip)
- 4 field mushrooms, peeled, if you like, and stalks removed
- 1 courgette, sliced lengthways into 4 slices
- 4 burger buns
- 2 tbsp mayonnaise
- 1 tsp chilli oil (use the chilli flakes from the bottom of the jar for a better flavour)
- 4 lettuce leaves
Method
- STEP 1
Stir-fry the red onions in the sesame oil until tender and cooked through, about 8 mins. Set aside and keep warm.
- STEP 2
Meanwhile, put the dark soy sauce and butter in a pan and melt together, then add the oyster sauce and stir. Brush the mixture over the mushrooms, then leave for a minute so the mushrooms can absorb the sauce. Heat the grill to high.
- STEP 3
Grill the mushrooms until tender, about 10 mins. When ready, you should be able to slip a knife through the thickest parts quite easily.
- STEP 4
Grill the courgette slices until they start to blister, and are brown and tender. Warm the burger buns briefly under the grill, and mix the mayonnaise with the chilli oil.
- STEP 5
Brush the base of each burger bun with some chill mayo, then add a courgette slice, lettuce leaf and mushroom. Top with some stir-fried onions and the bun tops.
