Preheat oven to 200c, fan setting. Wash and dry your Brussel sprouts. Place them in a baking tray with a good drizzle of olive oil, salt and pepper. Give it all a really good mix and roast in the oven for 15-20 minutes until cooked. While your Brussel sprouts are cooking in the oven make your pesto; place all of your ingredients in a food processor and whizz until smooth – adding in a little water if needed. Once your Brussel sprouts are cooked, remove from the oven and mix through your pesto. Sprinkle with a handful of roasted almonds and enjoy.
