Sweet potato burritos

Preheat the oven to 200ºC / 180ºC fan / gas mark 6. Place the cubed sweet potato on a baking tray and toss with the olive oil and spices. Season with sea salt and freshly ground black pepper. Cook in the oven for 25-30 minutes, or until tender.

To make the dressing, whizz together all of the ingredients in a small food processor or with a hand blender, until smooth. Season with sea salt and freshly ground pepper. Add a little water until you achieve the consistency you want, a tablespoon at a time.

To assemble the burritos, warm the tortilla wraps according to the packet instructions. Place on the work surface and divide the sweet potato between the 4 wraps. Top with the rice, kidney beans and spring onions, then drizzle with the avocado dressing. Fold in the outside edges, then roll to enclose the filling.
