Wash and thinly chop mushrooms in chopper. If you don't have chopper, you can chop them with knife.
Take them out in a bowl.
Chop onion and add in separate bowl.
Also chop coriander leaves, green chilies, ginger and garlic.
Take them out in the same bowl carrying chopped onion. Keep aside.
Take a pan and add chopped mushrooms in it.
Put the heat on high and start stirring it.
Mushrooms will release water. Keep cooking.
When there remains very less water, bring the heat to low and stir.
When water is completely evaporated in 10-12 minutes, transfer the mushrooms in a bowl and leave them to cool down completely.
Add crumbled tofu and chopped onion & coriander mixture.
Then add red chilli powder, turmeric powder, black pepper powder, garam masala, roasted cumin powder, dry mango powder, chaat masala and oil.
Mix them well.
Now start adding cornflour, little at a time.
Form a soft but shapable dough. In making this dough, we used 6 tbsp cornflour.
Place the dough in refrigerator for 15 minutes for easy handling.
Using wet hands, wrap the dough around skewers giving it a cylindrical shape, like that of a seekh kebab.
Put them in greased air fryer basket and apply oil on it. If you don't have airfryer, you can grill them in oven or even directly on gas stove over grill rack.
Air fry @180°C for 10-12 minutes.
Mushroom kebabs are ready.
Enjoy.
