Instead of frying the filling you can just mix it all together, omitting the water and not forgetting to add the olive oil. The end result is virtually the same, frying makes the rice firmer & the overall flavour slightly deeper.
This is a Spring/Summer dish, but you could mix it up and try using other vegetables such as courgettes and aubergines.
You can make this recipe adding mince meat. Simply add 250g of meat after the rice stage.
