Roasted sweet potato, cauliflower and fennel salad with hazelnuts and feta

This is a great vegetarian salad that is substantial enough for dinner. Roasting the vegetables and serving it still warm really makes it feel more hearty too. The combination of cauliflower, sweet potatoes fennel and feta is wonderful and the hazelnuts are the perfect finisher. Great for a mid-week dinner and one you can easily change to your tastes and based on what you have in the fridge!
