Sweet potato golgappa khatti meethi chaat is a delicious and tangy street food dish from India. It is made with crispy golgappas (hollow puris), filled with a mixture of boiled sweet potatoes, chickpeas, and spices. The chaat is then topped with a sweet and tangy tamarind chutney, yogurt, and a sprinkle of chaat masala. This chaat is a perfect blend of flavors and textures, with the sweetness of the sweet potatoes, the tanginess of the chutney, and the crunchiness of the golgappas.
