Cut a lid off the peppers and clean the inside.
Knead the minced meat with quinoa, onions, carrot, garlic, 1 teaspoon harissa, 1 teaspoon thyme, salt and pepper and fill the pods.
Sauté the excess mixture in 1 teaspoon olive oil, fry the tomato paste, deglaze with the vegetable stock, add the bay leaf, harissa and chunky tomatoes. Season with salt and pepper.
Put the peppers in the sauce and cook for about 30-40 minutes with the lid closed and low heat.
