Preheat oven to 150 degrees (fan bake). Spread tomato sauce on top of the pizza base.
Drain the oil from can of tuna and spread tuna on top of the base.
Spread the grated cheese evenly. Then lastly sprinkle the herbs to decorate.
Bake in the preheated oven until the cheese has melted and the pizza turns golden brown.
There is no right or wrong as to what can go on top of this pizza. Choose your topping, add can of beans, salmon or chicken or veges, whatever goes!! It all depends on your budget. All you need is a good base of tomato sauce and lots of cheese :-)
