Remove seeds from the dried chilli pepper if you prefer less heat, then roughly chop it.
Fry the minced meat in a large, deep coated pan over medium heat, breaking it apart as it cooks and seasoning with salt and pepper, until cooked through with no pink remaining (approximately 5-8 minutes).
Add the vegetable stock, rice, frozen spinach, and chopped chilli pepper to the pan.
Stir well, then cover with a lid.
Simmer over medium heat for 18-20 minutes until all liquid is absorbed and the rice is tender.
