A celebration of the humble sweet potato. Here we roast them as wedges, as well as blend them to create our very own homemade queso. Delish.
Preheat the oven to 200°C fan/220°C/gas 7. Put the cashews into a bowl, cover with hot water from the kettle, and set to one side to soak.
Dice 200g of the sweet potatoes into 1cm pieces and place in the corner of a large roasting tray. Slice the remaining sweet potatoes into wedges, then place at the other end of the tray. Season the wedges with ½ teaspoon of salt and a large pinch of pepper, drizzle over 2 tablespoons of vegetable oil, and toss to combine. Slice 1 red onion in half, skin on, and add it to the tray along with the garlic cloves (skins on). Roast for 20 minutes.
For the salsa, cut the mango in half around the stone, score the halves in a criss-cross pattern and scoop out the flesh. Dice the red pepper, discarding the core and the seeds. Peel and dice the remaining red onion and roughly chop the coriander leaves, discarding the stalks.
Add everything to a mixing bowl along with the juice from half the lime, and a pinch of salt and pepper. Mix everything together.
Take the tray out of the oven and remove the onion, garlic cloves and diced sweet potato. Move the sweet potato wedges around the tray, then return the tray to the oven for 10 minutes.
Drain and rinse the black beans. Add them to the tray along with the Cajun seasoning and gently give everything a mix. Roast for 10–15 minutes, or until the sweet potato is lightly charred.
To make the queso, drain the cashews and transfer them to a high-powered blender or food processor, along with the diced sweet potato, roasted red onion and garlic (skins removed from both), nutritional yeast, juice from the remaining lime half, milk, half the red chilli (seeds removed), and large pinches of salt and pepper. Blend until smooth.
Remove the wedges from the oven and scatter over the salsa and half the queso. Thinly slice the remaining chilli and roughly chop the rest of the coriander leaves. Cut the avocado in half, scoop out and slice the flesh, then add it to the wedges, along with the sliced chilli and coriander leaves. Serve alongside the remaining queso. Epic.
