Heat 2 tbsp vegetable oil in a large saute pan or wok, over medium-high heat. Add 1 cup white rice. Cook rice, stirring constantly, for several minutes, until rice begins to turn a golden colour.
Reduce heat to low. Gently pour in 500ml warm water, then 250g passata and stir.
Stir in:
Turn heat back up to medium-high, bring to a boil, then reduce to low and cover. Simmer for 10m, or until all water has been absorbed.
Add ½ cup sweetcorn (optional) and more water if the rice is looking dry. Simmer for 10m more.
Turn off heat, fluff rice then let sit, covered, for 5-10m before serving.
