1In a large mixing bowl, combine the grated carrot, finely chopped onion, finely chopped tomato, finely chopped soyabean, and minced garlic.
Add salt, black pepper, and chili powder to the vegetable mixture and mix well.
In another bowl, mix the rice flour with enough water to form a smooth dough. Knead the dough until it is soft and pliable.
Divide the dough into small balls and roll each ball into a thin circle.
Place a spoonful of the vegetable mixture in the center of each dough circle.
Fold the edges of the dough over the filling and pinch to seal, forming a momo shape.
Steam the momos in a steamer for about 10-15 minutes or until the dough is cooked through.
Serve the vegetable momos hot with your favorite dipping sauce.
