Leftover Roast Vegetable Crumble


It is always difficult to be creative after Christmas with your recipes, especially when you have spent so long building up to the big day. And there is always lots of food to use up that you have no idea what to do with! This is one of my favourite, easy meals that is delicious and nutritious and uses all ingredients that you will already have in your cupboard! The nutty flavour of the rich sauce compliments the sweetness of the parsnips and the bitterness of the sprouts perfectly in my dish, but you could use any vegetables you have. And for me, the more topping the better as it really makes this feel like a substantial meal. Alternatively, if you are stuck for side dish ideas and you have guests, this would be a great option! Serves two-three as a main or four as a side!
