Take a non-stick pan and heat 1 tsp oil on it. Sauté cumin seed, chopped onions, and green chili for about 2 minutes and then add grated carrots and green peas.
Cook for 2-3 minutes. Switch off the flame. Mash these vegetables. Let them cool down.
In a separate bowl take wheat flour, gram flour, cornflour, salt, sugar-free, butter, baking powder, and mashed vegetables. Mix everything with hands to a coarse breadcrumb-like mixture.
Add 1 tablespoon milk at a time till you get a smooth dough. I added 2 tablespoons of milk.
Now cover the dough with a cling wrap and refrigerate it for 30 minutes.
Meanwhile, keep the oven for preheating to 160 °C.
After 30 minutes take the dough out of the refrigerator and slice the cookies using a sharp knife
Arrange the cookies on a greased baking tray and put them to bake in preheated oven for 15-18 minutes.
When baked, take the cookies out from oven and transfer them to a cooling rack.
Let the cookies cool down completely before serving.
