Prepare the Veggie Mix: In a large mixing bowl, combine the boiled corn, chopped onion, tomato, capsicum, carrot, and cabbage. You can also add French beans or spinach if available. Add the chopped coriander leaves.
Add Flours and Spices: Add the Gram flour (Besan), All-purpose flour (Maida), and Cornflour to the vegetables. Add the crushed ginger-garlic-chilli paste, salt, and turmeric powder.
Make the Batter: Add water gradually and mix well to form a thick batter. It should not be runny; it needs to be spreadable. Add grated cheese and half a teaspoon of butter to the batter for extra flavour and mix again.
Coat the Chapati: Take a leftover chapati. Spread a generous layer of the vegetable batter evenly on one side of the chapati.
Pan Fry the Pizza: Heat a tawa (griddle) on medium flame. Drizzle some oil or butter. Carefully place the chapati on the tawa with the batter side facing down.
Cook Until Crispy: Cook on low-to-medium heat to ensure the veggies cook through and the crust becomes golden brown. You can drizzle a little oil around the edges.
Flip and Roast: Once the bottom layer is crispy and releases from the pan easily, flip the chapati. Roast the plain side for a minute until crisp. Press down gently with a spatula to cook evenly.
Garnish and Serve: Remove from heat. Top with extra grated cheese, tomato ketchup, or mayonnaise if desired. Cut into slices and serve hot!
