Preheat the oven to 200*, and boil some water.
Cook the brown rice for 20mn, and half way through add the quinoa.
Put the chickpeas on a baking tray; add the paprika and 2 tbsp of olive oil; season and stir to coat evenly, then roast in the oven for 20mn. Add the walnuts for the last 5mn.
Roughly chop the nuts.
Mix the lemon juice, maple syrup, garlic, herbs and 3 tbsp of olive oil in a small container, and season. Mix well.
Once the rice and quinoa are cooked, transfer to a large bowl; add the chickpeas, nuts and most of the dressing.
Fold in the blueberries, the feta if using and salad leaves.
Spoon into serving plates and add the rest of the dressing, plus some herbs to decorate.
