First Put two cups of oats & 1 cup of sooji in a big bowl. Then put Curd one cup, start mixing. If you feel it's getting dried, then add water but don't make the batter watery. We will add water later stages. With curd oats become soft over time. So the time required to finish chopping Vegetables is enough.

Add salt, Maggi masala & black pepper as per the taste. Know this, once you put all the vegetables, you might need to add more salt.

Start chopping each vegetables into small cubes. Please don't grind or use hand chopper. Best option is to use knife. It's time taking but it will be better. If you have instrument which can chop into small pieces then also better.

The amount of veggies as per your taste. Normally I use one from each vegetables except garlic which is around 10-15, cabbage i.e., ~100gm, brocolli also ~100gm, paneer ~200gm, button mushroom ~ 7-8 pieces.

Keep adding veggies to the batter as you go, no need to store in a seperate plates. Mix well once all veggies are chopped. Add water and salt as per your taste. Don't make the batter two watery.

Switch on the gas & Heat the pan (recommended non stick pan). As it reaches medium heat, put better twice using a karchi/milk ladle on the pan. Use the karchi to spread the batter a bit and make sure it's round like set dosa. Put some oil around the uttapam. Then Simmer down and leave it for few mins.

Start clearing the sides just like we do while making plain dosa. Add some oil on the top side. It's time now to flip the uttapam. Once flipped leave it for few mins for the top side to be cooked properly.

As it gets cooked, the color changes to golden and then dark. Try not to cook with high flame. Though the buttom side might cooked but the inside won't. Slow or medium is preferable. Golden color is good for taste. If you want little more dark color, then you can increase the flame once it's cooked and leave for max 1 min.

Then you can serve this on plate with ketchup or anything equivalent. Better can stay upto 6-7hrs max in case left out. If you keep for more hours, then the curd in the ingredients will start making the batter more khatta.

You can use edible oil or butter or ghee to make it. Another reason to use non-sticky pan and low flame is to use less oil and make it. It's healthy and once you have like 2/3, you won't feel hungry for quite a bit of time.
