Microwave frozen peas and carrots with water for 3 minutes (save the water because that will be used later on)
Mix semolina (suji) and yogurt in a bowl
Add peas and carrots, tomato, water (from the first step), salt, and red pepper powder to the bowl
Mix well and keep aside for 15-20 minutes [see picture below]
Put the oil in a round bottom skillet pan and heat it
After waiting for 15-20 minutes, add the baking soda to the mixture
Mix well
Pour the mixture into the round bottom skillet pan [see picture below]
Cover it with the lid and cook on medium heat until the bottom is golden brown (5-7 minutes) and the upper portion is slightly set
Flip the cake carefully and continue to cook until the bottom is golden brown [see picture below]
Once both sides are golden brown, take the cake out of the skillet pan and put it in a plate
Cut into 6 pieces and serve with ketchup and/or mint chutney
