Optional: 1 punnet of small mixed peppers, deseeded and cut in half
Preheat the oven to 180˚. Drizzle some olive oil on the oven tray. Cut cauliflower into steaks and place it on the tray. Rub olive oil and garlic over the cauliflower. Brush harissa paste on the cauliflower and place it in the oven. Cook for 5 minutes, add peppers if you wish, and cook for another 10 minutes.
Add olive oil to a frying pan and the remaining garlic. Rub salt and pepper on both sides of the steak and fry in the pan. Depending on the heat of your pan and how you like your steak to be cooked, a medium rare steak will take you approximately 3 and half minutes on each side and let it rest for 4 minutes. Smear the hummus on your plate. Top with steak and grated parmesan, place the cauliflower steaks on top and finish off by sprinkling crispy onion bits.
