Super Easy. This is a tasty all in one dish that is a amazing way to use lots of organic veggies. The spice of the harissa paste works so so well with the leeks and beetroot. A jar of store bought harissa is a handy ingredient to have in the fridge, they do vary in spiciness so have a taste before adding to your dish.
You can use quinoa for a gluten free version, please see method below, omit feta to make this dish vegan friendly.
