Heat oven to 220C/200C fan/gas 7 and line a baking tray with baking parchment. Slice the cauliflower into two 1-inch steaks – use the middle part as it’s larger, and save the rest for another time. Rub the paprika and 1⁄2 tbsp oil over the steaks and season. Put on the tray and roast for 15-20 mins until cooked through.
Meanwhile, make the salsa. Chop the pepper, olives, parsley and capers, and put into a bowl and mix with the remaining oil and vinegar. Season to taste. When the steaks are cooked, spoon over the salsa and top with flaked almonds to serve.
