Remove hard centre stalk and leaves from cauliflower. Slice cauliflower into steaks about 2 cm thick.
Heat BBQ to medium. Put the spices and oil in a shallow bowl and stir to combine, add cauliflower, and turn ensuring both sides are well coated. Use a pastry brush to ensure mix gets into all the cracks.
Cook steaks on BBQ for 10 mins each side, or until tender. Turning occasionally to ensure spices don’t burn. Finish with a squeeze of lemon juice.
Transfer to a plate, scatter with almonds and mint leaves. Serve with Greek yogurt.
