Crumble the stock cubes onto the Lékué rice cooker. Add the chopped onion, chilli, peppers, peas and spices. Pour in the boiling water and stir until the stock is dissolved.
Add the rice and hot sauce (if you're using it) then stir.
Pop the lid on and cook in the microwave on high power for 12 minutes.
Remove from the microwave and give it a stir with a fork. Check the rice is cooked and the water has absorbed. If it's not quite cooked, add a little more water and cook for another minute or two.
