Bring the rice to the boil with twice the amount of salted water in a saucepan, then cook over medium heat until the water has been completely boiled or absorbed.
Wash the vegetables, cut the bell pepper into strips, the mushrooms and the courgette into slices. Heat the oil in a pan, add the vegetables and season with salt and pepper. Fry in the pan for about 8-10 minutes, turning over and over again so that nothing burns.
Mix the rice with the vegetables in the pan, as well as the corn. Fry everything again briefly, adding curry powder, salt and pepper to taste.
