This recipe is a total favourite for the vegetarian in my life. The polenta really makes you rethink why you’d ever bother to peel and boil potatoes for mash. This is way creamier and far more indulgent. The contrast between the charred crisp cauliflower, the soft flavoursome leeks and the garlic pesto all served on top of a serious mound of creamy heaven is an all round winning combination. Perfect for a dinner party and easy to prepare well in advance.
