For a cheesy twist on scallion pancakes, try adding some grated cheese to the filling. The cheese melts and becomes gooey when the pancakes are cooked, adding a rich and creamy element to the dish. Cheddar, mozzarella, or even feta cheese can be used, depending on your preference. Serve these cheesy scallion pancakes as a snack or a side dish, and enjoy the combination of the savory scallions and the melted cheese.
