Why not just buy quinoa and rice and cook it yourself- cheaper and you know exactly what is in it, plus no issues about cooked food sitting in plastic and being re-heated.
If you like the flavourings, experiment with your own herbs and spices- you can save time by making a batch of spice paste and freezing it in an icecube tray- when you cook the rice/quinoa- drop an icecube or two in there and it is ready to go!
