Prepare the hummus (you can use store-bought or follow THIS recipe for home-made).   Heat the oven to 375F (190C). Wash the potatoes and cut lengthwise into wedges—season with salt, pepper, and spices (coriander, cumin, paprika).   Then grease with olive oil and place in an ovenproof dish or on a baking tray. Bake for about 30 - 35 minutes (or until soft).   Serve the roasted potatoes on a bed of hummus (recipe can be found on page 12) and pesto.
