In a bowl add maida, salt. Mix it then add water little by little and Knead it into a soft dough. Cover the dough with a damp cloth and rest it for about half an hour.

Rest it for some more time by again covering it with a wet cloth. Now for chicken filling, first take the chicken pieces & cut it into small chunks. Now put it in a grinder. Then add chopped onion, chopped spring onion, green chilli sauce, chopped green chillies, ginger-garlic paste, salt, 1 tsp oil & grind everything well. You will notice that the chicken filling has now become lumpy...

Now add some chopped bell pepper & coarsely grounded roasted walnuts. Mix everything well & keep this mixture in a refrigerator for about 15 mins.

Now take orange dough portion and roll it out like chapati. Keep it aside. Then roll the white one then finally the green one.

Now place one above the other & start rolling it from either side as shown in the image below.

Roll it well by giving it a gentle pressure. Remove the sides & cut it into 10 to 12 equal portions.

Gently press & flatten each of the tri-colour balls. Now give gentle pressure & roll each one of them into a puri-kind as shown below.

Now put a tbsp of chicken & walnut filling in the centre & fold it from between by sealing it's edges. Now join both the edges to give it a proper shape.

Do the rest with the same process. Now you can either put them into a steamer & steam it for 10 to 12 mins. Or you can put them into a strainer. Now steam the momos using double-boiler method for 12 mins. I.e boil some water in a big bowl then place the strainer over it & cover it. Keep the flame low and steam it.

After 10 to 12 mins., just switch off the flame, remove the momos on a platter & serve hot with some schezwan chutney or with any ketchup of your choice.
