In a mixing bowl, mash the cooked rice slightly for a smoother texture.
Add chopped vegetables, grated cheese, soy sauce (optional), black pepper, salt, and cornflour to the rice. Mix well to form a dough-like consistency.
Take small portions of the mixture and roll them into bite-sized balls or desired shapes.
Heat oil in a pan on medium heat for frying the dumplings.
Gently place the dumplings in the hot oil and fry until they turn golden brown and crispy.
Remove the dumplings from the oil and place them on paper towels to drain the excess oil.
Pack the crispy rice dumplings in your kid’s lunchbox with ketchup or a dipping sauce.
