This is a little different method for making pizza having toppings with white sauce.
What you need:
Milk, cream (depending on how health conscious you are)
Cheese (optional for health conscious people)
Vegetables of your choice for the toppings chopped (Baby corns, or sweet corn, red or yellow bell pepper, capsicum, French beans, carrot, cherry tomatoes)
Preferably, take a nonstick pan for making the topping. Pour milk in the pan add corn flour keep stirring to thicken it evenly, add cream, cheese let the cheese melt. After all the ingredients have properly melted add the chopped vegetables to it. Let all the vegetables cook well. Add Italian herbs, salt to taste and pepper powder to it.
Roast the pizza base on a separate pan and apply a layer of ketchup to it. Pour the toppings cooked in white sauce over it . Serve hot.
Tip: You can even make this over garlic bread as a starter, instead of meal.
