In a mixing bowl, add 1 cup besan, 1 cup jowar flour, and ½ cup rava. Then add salt to taste, ½ tsp turmeric powder, 1 tsp red chili powder, 1 tsp chaat masala, 1 tsp cumin powder, ½ tsp black pepper powder, ½ tsp garam masala, ½ tsp ajwain, and 2 tbsp white sesame seeds. Mix well.
Gradually add 1.5 cups of water and make a thick batter. Cover and let it rest for 15-20 minutes.
In a mixer jar, add 3 green chilies, 1-inch ginger, 5-6 garlic cloves, and 1 tsp cumin seeds. Grind them into a paste and keep it aside.
In the same mixer jar, add 1 cup of roughly chopped cabbage and grind it on pulse mode without adding water. Keep it aside.
Now, add 1 cup of chopped carrot and ½ cup of green peas to the mixer jar. Coarsely crush them using pulse grinding and keep them aside.
In a mixing bowl, add 1 cup of chopped cabbage, 1.5 cups of crushed carrot and green peas, ½ cup of chopped tomatoes, ½ cup of chopped capsicum, 1 cup of grated cucumber, 1 cup of chopped spinach, the ground green chili-ginger-garlic paste, 2 tbsp of chopped mint leaves, and ½ cup of coriander leaves. Mix well. The vegetable mixture is ready.
Add the vegetable mixture into the batter, along with a pinch of salt and 1 tbsp of lemon juice. Mix well.
The batter should be thick. If it is slightly thin, add some rava to adjust the consistency.
Heat a pan and add some oil. Sprinkle sesame seeds in it.
Pour 1 ladle of batter and spread it evenly. Cover and cook on low flame.
After 5 minutes, flip it and cook the other side on low flame until golden brown.
Once cooked on both sides, remove from the pan and repeat the process for the remaining batter.
You can also cook the chilla on an iron tawa (refer to the video).
Serve hot chilla with green chutney or dahi.
