Place the diced onion and red pepper in a reasonably large non-stick saucepan. Cover with a lid and cook over a gentle heat for 3 minutes until softened but not browned.
Remove the lid and stir in the chilli flakes, turmeric and smoked paprika. Cook for 2 more minutes. Add a splash of water if it starts to get a little dry.
Add the rice and stir to coat with the spices. Add the chicken stock, salt and pepper. Turn the heat up and bring to the boil. Then cover with a lid and turn the heat down low. Cook for 7 minutes, or until the rice is nearly cooked (check the rice cooking instructions.)
After 7 minutes (depending on rice cooking instructions) add the peas and stir. Re-cover with the lid and cook for 3 more minutes or until the rice is done to your liking and the peas are hot.
