Break the cauliflower up into bite sized florets and place in a mixing bowl. Add the olive oil and crushed garlic, stirring well to coat. Lay on a baking tray and roast at 190 C for 30 minutes, turning halfway through.
Once cooked allow to cook to room temp then put the cauliflower back in the original mixing bowl. Scrape up any crispy bits of roasted garlic and add them in too. Add in the capers, olive halves, onion and as much lemon juice as you like to taste. I added just over half a tbsp.
Season with pepper, put into a serving dish and then sprinkle with pine nuts and the parsley at the end. Serve at room temperature
