Take a bowl and in the bowl, mix semolina with curd, water and all the spices. Keep this batter aside for 10 minutes.
Heat a pan and add oil. Once the oil is hot, add mustard and cumin seeds. Add chopped onion and saute it for 5 min. Add chopped beans, chopped bell pepper and peas to onions and continue to saute these vegetables for another 5 minute.
Add sauted vegetables along with grated carrot, ginger and green chillis to the batter and make a smooth batter of medium consistency.
Now add baking soda and transfer the mixture into a greased mould (I used a silicon mould to avoid any greasing). Sprinkle chilli flakes and oregano on top of it. Keep this mould in a preheated oven @180 C for 20-25 min or till it passes the toothpick test.
Slice it once it comes to room temperature and serve it with your choice of sauce.
