Peel and finely dice the onion, clean the remaining vegetables and cut everything except the garlic into medium-sized cubes. Heat the oil in a deep pan or pot and first sauté the onions until translucent, then add the diced vegetables and sauté well.
Add salt and pepper.
Add tomato paste and ajvar and sauté briefly. Add the garlic cloves. Add the couscous and deglaze with water. Let the couscous swell on low heat. Stir in between.
Season with balsamic vinegar, broth, salt, pepper, sugar and paprika powder. If you like it spicy, you can add some harissa paste. Dose carefully, it is really hot!
