1In a large bowl, mix the all-purpose flour with a pinch of salt and enough water to make a smooth dough. Knead well and set aside for 30 minutes.
Heat the vegetable oil in a pan over medium heat. Add the ginger-garlic paste and sauté for a minute.
Add the finely chopped onions, cabbage, carrots, and bell peppers. Stir-fry for 5-7 minutes until the vegetables are tender.
Add the soy sauce and salt to taste. Mix well and cook for another 2 minutes. Remove from heat and let the filling cool.
Divide the dough into small balls and roll each ball into a thin circle.
Place a spoonful of the vegetable filling in the center of each circle. Fold the edges and pleat to seal the momos.
Steam the momos in a steamer for 10-12 minutes until they are cooked through.
Serve hot with your favorite dipping sauce.
