Portobello burger with grilled beef

Method

Step 1.
Heat a barbecue until hot. 

Step 2.
Halve the pepper and remove the seeds, then cut into thick strips. Clean the mushrooms, cutting out the stalks. Slice the gherkins. Peel the onion and cut into fine rings. 

Step 3.
Rub the steak with 1/2 tbsp olive oil and season with salt and pepper. Drizzle the mushrooms and peppers with the remaining oil and season. 

Step 4.
Grill the steak on the barbecue for 3-4 minutes on each side, then leave to rest for a few minutes. Cook the mushrooms and peppers on the grill for 4-5 minutes, turning, until tender and starting to char.

Step 5.
To serve, cut the steak into slices. Top four of the mushrooms with half the rocket, the onion rings and peppers. Arrange the steak strips and the remaining rocket on top and finish with a second mushroom. Secure with skewers.

Step 6.
Mix together the mayonnaise and yoghurt with the herbs and lemon juice, season and serve in a small bowl with the ‘burgers’.

Tip:

Cook the steak and vegetables on a hot griddle pan instead of a barbecue if desired. 

Serves 4.
