Shake up your midweek meals with these colourful veggie tacos. With their natural sweetness, crispy edges, and a hint of spice, sweet potatoes are the ultimate taco filling, especially when topped with zesty tomato salsa, sour cream, or whatever toppings you love, frankly.
Based on 4 servings, adjust as needed.
Put the onion in a bowl with two thirds of the lime juice and a tsp of salt. Leave to pickle for an hour.
Heat the oven to 200C/180C fan/gas 6. On a large, flat baking tray toss together the sweet potatoes, oil, spices and some seasoning. Roast for 30-35 mins, turning halfway through, until golden and crispy. Once cooked, toss with the black beans.
Mix the avocado and tomatoes with the remaining lime juice and a pinch of salt. Warm up the tortillas and pile on the sweet potatoes and beans. Top with the avocado, tomatoes and pickled red onion, and crumbled feta, soured cream and coriander, if using.
