In a bowl, combine the cabbage, carrot, garam masala, red chili powder, salt, half the ginger-garlic paste, all-purpose flour, and cornstarch. Mix well.

Heat oil in a pan. Shape the mixture into small balls and fry them on medium heat until crispy and golden brown.

In another pan, heat 2 tablespoons oil. Add the chopped onion and green onions, and sauté. Add the remaining ginger-garlic paste and sauté until fragrant. Add tomato ketchup, chili sauce, and soy sauce, and cook for a minute. Then add vinegar and black pepper powder, mix well, cover, and cook for 2 minutes.

Add the fried cabbage balls to the sauce, mix well, and cook for 2-3 minutes. Turn off the heat, garnish with cilantro and green onions, and serve.
