2. Cook the rice in boiling water until al dente, about 35 minutes. Drain and set aside in a bowl.
3. Whilst the rice is cooking, combine the oil and onions in a large non-stick frying pan and cook over moderate heat until soft, about 5 minutes, stirring frequently. Add garlic and stir for one minute more.
4. Add zucchini and cook 5 minutes, until crisp and tender, then stir in oregano and season with coarsely ground black pepper.
5. Add zucchini mixture to the rice, together with the cherry tomatoes and ricotta. Mix well.
6. Spread evenly in an ovenproof dish sprayed with mono/polyunsaturated oil cooking spray. Scatter with parmesan. Cover with foil and bake for 20 minutes. Remove foil and cook a further 20 minutes or until top in golden and filling is bubbling.
