Place ground turmeric, ground coriander, garam masala, red chili powder, minced garlic, minced ginger, enough salt and 1 tablespoon oil in a small bowl. Combine together to form smooth paste. Rub the paste onto the chicken. Leave to marinate for 30 minutes in the refrigerator.
To cook chicken: Heat remaining oil in a frying pan over medium-high heat. Add chicken. Cook until all the sides are browned or the chicken is no longer pink inside. When done, shred chicken into small pieces. Set aside.
To make dosa pizza: Heat a tawa over medium-high heat. When the pan is hot, add ⅓ cup batter to the center of the pan. Use a spoon or ladle to spread it as thin as possible, leaving the sides raised like a regular pizza.
When the pizza starts to cook, reduce the heat to medium-low. Spread a teaspoon of tomato paste on it. Arrange shredded chicken on top. Sprinkle with mozzarella cheese. Add the vegetables on top. Sprinkle with more cheese.
Cover the pizza dosa with a lid. Cook for 3-4 minutes or until the veggies are soft and tender. Continue with rest of the batter and toppings until used up.
Serve as breakfast, snack, lunch or dinner.
