Boil 2 cups water in a pan and switch off the flame. Add the soya chunks and let it soak for 5 to 6 minutes.
Drain the water from soya chunks and now rub and rinse in clean water for 3 times.
Squeeze the soya chunks thoroughly and get rid of all the excess water in it. Keep it aside.
Blanch the spinach in boiling hot water for 2 minutes. Drain the water and transfer to ice cold water to stop the cooking process and retain the colour.
Squeeze out all the excess water from the spinach and keep aside.
In mixer jar, add the chopped onion, garlic, ginger, green chillies, coriander and mint leaves and grind.
Next add the green moong sprouts and pulse grind.
Finally add the soya chunks and blanched spinach/ palak. Grind well to a smooth paste. Do not add water.
Transfer the ground paste to a bowl and add all the dry spices, salt, rice flour, gram flour and corn flour. Mix well and bring it together into a smooth and non-sticky dough.
Let the dough rest for 5-10 minutes.
Now take a small chapati sized dough and roll and then flatten. Roll the edges over counter top. Prepare tikkis with the remaining dough.
Heat a skillet and add oil to it (for shallow frying). Place the tikkis in skillet with gap in between. Cook on low to medium flame till one side is golden brown.
Now carefully flip the tikkis. Cook the other side as well till golden brown. Transfer to a tissue paper to absorb any excess oil.
Cook all the remaining tikkis in same way. Serve with green chutney and mayo dip and a salad by side.
