How is "Sattu Ka Paratha" prepared, and what makes it a nutritious and popular choice in Uttar Pradesh's cuisine?

Sattu Ka Paratha is a nutritious and flavorful flatbread that is popular in Uttar Pradesh, especially during the summer months. To prepare it, a filling of roasted gram flour (sattu), mixed with chopped onions, green chilies, and spices like ajwain (carom seeds) and amchoor (dried mango powder), is stuffed into a wheat flour dough. The stuffed dough is then rolled out into flatbreads and cooked on a griddle with ghee or oil until golden brown and crispy. Sattu, being rich in protein and fiber, makes this paratha not only delicious but also highly nutritious, making it a favorite choice for a wholesome meal in Uttar Pradesh.
