Remove the ends of the beans, wash them, and cut them into 2 or 3 pieces each.

In a saucepan, heat 2 tablespoons of olive oil and fry the onion slices until they become tender.

Add the green beans, the garlic cloves, salt and just enough water to cover the bean mixture. Stir and let it simmer until the beans slightly change color.

Add in the tomatoes, tomato paste, the remaining olive oil and sugar. Mix again.

Reduce the heat, cover and let it simmer for 30 min or until the beans are tender and the sauce has thickened.

Serve cold with pita bread.
