Roasted mushrooms on white bean mash

Harissa paste, a vibrant North African blend of chilli and spices, makes a quick and easy marinade for the portabellini mushrooms as well as the lamb steak variation, while the salsa topping adds crunch and colour to both options. You could also try a spoonful of Romesco Sauce or the North African-inspired Tahini Dressing instead of the salsa with the mushrooms or indeed the lamb.
