This smoky-sweet side dish is all about bold, earthy flavour. Soft sweet potato cubes are roasted to caramelised perfection and combined with roasted poblano peppers, whose mild heat adds a touch of warmth and depth. Tossed with a simple but flavour-packed spice blend and finished with a squeeze of lime and chunks of avocado, this dish makes a vibrant and colourful addition to any Mexican spread.
