To make Veggie Manchurian: In a bowl, combine cabbage, carrot, green beans and scallions. Add the all purpose flour, corn starch and salt & pepper. Mix well. The quantity of the flours is not much — it is only to bind the veggies when you squeeze them into balls. The ratio of veggies to flour ratio is much higher — but if you find that the manchurain balls are not holding shape while frying, then add more flour to bind them well — add flour 1tbsp at a time.
