Vegetables in white sauce

We usually prepare white sauce using refined wheat flour (in India called as maida) but in this recipe we are using whole wheat flour to make it a healthy meal. This is a complete healthy food for kids or even adults, since it contains all vegetables and requires less oil. You experiment with this recipe using any vegetable of your choice.

Ingredients:
1/2 cup baby corns; each cut into 3 pieces,
1/2 cup mushrooms,

4-5 cinnamon sticks (dalchini),
8-10 peppercorns (kalimirch),
