Cut the cauliflower leaves off and pluck equal sized florets. Dunk them in a bowl of hot water and a teaspoon of salt. Peel the potatoes and dice them up in the same size as the cauliflower florets. Take a handful of frozen peas and add them to a bowl of hot water as well. Chop your onions, green chillies, ginger and garlic. Puree the tomatoes and keep aside. Place a medium-sized pan on medium heat. Add 2 teaspoons of cooking oil. Once the oil is warm, add the jeera and bay leaves. Toast for 10-15 seconds.
Next, add the ginger, garlic, green chillies and onions. Saute them all together until the onions are soft.
Now, add the tomato puree and all the spice powders - turmeric, red chilli, coriander and jeera. Mix all of them well and cook them with the pan closed for about two minutes.
To this onion-tomato base mixture, add the cauliflower florets and potatoes. Mix well until all the pieces are coated with the base mixture. Add salt and mix again.
Add 1/2 cup of water and close the pan with a lid. Let it cook for 8-10 minutes. Check the water level in the pan regularly while checking the progress of the doneness of the vegetables as well.
Once the vegetables have cooked, add the thawed peas to the pan and mix well. Let all the ingredients cook without the lid for a minute or two while continuosly stirring.
Turn off the flame and garnish with coriander leaves and lemon juice.
