Grilled Steak Sandwich with Caramelised Onions and Mushrooms

If you want a vegetarian version, slices of grilled haloumi with tomato relish will go perfectly with the sticky onions and mushrooms.

2 large brown onions, thinly sliced

2 tablespoons each olive oil and butter

sea salt and ground pepper 2 cloves garlic, crushed

2 teaspoons finely chopped rosemary or thyme

6 large portobello mushrooms, sliced

1 tablespoon soy sauce

2 x 200-gram rib eye steaks or sirloin steaks TO SERVE 4 ciabatta rolls, warmed, halved, buttered

mayo, rocket leaves and mustard

Cook the onions with the oil and butter and a good pinch of salt on a barbecue hot plate until soft. Add the garlic, herbs and mushrooms and continue to cook, turning often, until tender. Sprinkle over the soy sauce and cook for a few minutes until glossy.

Season the steak with salt and pepper and cook on the barbecue grill until done to your liking. Set aside to rest then slice.

TO SERVE: Spread each of the ciabatta roll bottoms with mayo and top with rocket and steak slices. Add a squeeze of mustard then pile the onion mixture on top. Add the tops and eat immediately. MAKES 4
