Take all the chopped vegetables such as Carrot, Cabbage, Capsicum, French Beans and Spring Onion in a large bowl.
To it add Salt as required and mix it. Allow it to rest for 10 minutes. This is done to remove excess water from the vegetables so that the vegetables do not release water while preparing the Manchurian balls.
When the veggies release water, drain out the extra water by squeezing the vegetables with your hand. Now the veggies are ready which will help in proper binding of the balls.
Next, add All Purpose Flour, Corn Flour, Black Pepper Powder and Salt to the vegetables. Add Salt as required since we had already added it before also. Mix all the ingredients properly with your palm.
Do not add Water to it since the veggies will leave water from itself which will be sufficient to bind the balls. In case the mixture is little dry and you are not able to bind the mixture properly to prepare the balls, then you can add little amount of water.
Once all the ingredients are mixed properly, take small amount of the mixture in your palm and roll it to make a small ball. Keep it aside.
In the same manner, prepare small balls of required size for all the mixture and keep them aside in a plate.
Now switch on the stove and heat Oil in a kadai over medium flame.
Once hot, gently add the prepared Balls one by one into the oil. Do not overload the kadai with the balls.
Under medium flame, fry the balls till it changes its colour to golden brown and is crispy from outside.
When the balls are fried properly, take them out with the strainer and keep it over kitchen towel or tissue paper to absorb excess oil.
Similarly fry the remaining balls in batches. Veg Manchurian Balls are ready. Keep them aside in a bowl and cover it.
