Quite simple to make! 
I think, if you were to stir-fry the ingredients first, and make it
a bit 'wet', then throw in the stock to cook with the rice grain,
and then, when the rice is cooked, throw in the ingredients and
stir them into the rice, then cook for a while longer, it'll be
even better, because the goodness in the stock would have permeated
into the rice grains!
